Configuring color control for lighting devices

ABSTRACT

In an auto vibrancy mode, a vibrancy value for a lighting load may be automatically determined based on a selected color setting for the lighting load. The automatically determined vibrancy value may also be configured to emit light from the lighting load at or above a target CRI value for the selected color setting. The selected color setting may be a CCT value on the black-body curve or an x-y chromaticity value. If the selected color setting is CCT value on the black-body curve, the automatically determined vibrancy value may be a pre-defined vibrancy value that is configured to emit light from the lighting load at or above the target CRI value for the selected CCT value. If the selected color setting is an x-y chromaticity value, the automatically determined vibrancy value may be based on the distance between the selected x-y chromaticity value and the black-body curve.

BACKGROUND

A user environment, such as a residence, an office building, or a hotelfor example, may be configured to include various types of load controlsystems. For example, a lighting control system may be used to controlthe lighting loads in the user environment. A motorized window treatmentcontrol system may be used to control the natural light provided to theuser environment. A heating, ventilating, and air conditioning (HVAC)system may be used to control the temperature in the user environment.

A user of the load control system may configure the load control systemto perform as intended. However, as a single load control system mayinclude various types of load control systems (e.g., lighting controlsystem, motorized window treatment system, HVAC system, etc.), the usermay have numerous setting to configure for the load control system toperform as intended. Accordingly, the user may interact with a graphicaluser interface to accurately and efficiently configure the load controlsystem.

SUMMARY

The vibrancy settings of a lighting load may be configured by a user.For example, a lighting load may be set to one of an auto vibrancy modewhere a vibrancy value for the lighting load may be automaticallydetermined, or an adjustable vibrancy mode where a user may select anadjustable vibrancy value for the lighting load. When the auto vibrancymode is selected, the automatically determined vibrancy value may bebased on the selected color setting, and may be configured to emit lightfrom the lighting load at or above a target color rendering index (CRI)value for the selected color setting. For example, the automaticallydetermined vibrancy value may be based on the distance between theselected color setting and the black-body curve.

The selected color setting may be a correlated color temperature (CCT)value on the black-body curve or an x-y chromaticity value. If theselected color setting is CCT value on the black-body curve, theautomatically determined vibrancy value may be a pre-defined vibrancyvalue that is configured to emit light from the lighting load at orabove the target CRI value for the selected CCT value. Further, theautomatically determined vibrancy value may increase as the selected CCTvalue increases. If, however, the selected color setting is an x-ychromaticity value, a distance between the select x-y chromaticity valueand the black-body curve may be determined. If the distance between theselected x-y chromaticity value and the black-body curve is less than adistance threshold, the selected x-y chromaticity value may have anequivalent CCT value, and the automatically determined vibrancy valuemay be the pre-defined vibrancy value that is configured to emit lightfrom the lighting load at or above the target CRI value for theequivalent CCT value. If, on the other hand, the distance between theselected x-y chromaticity value and the black-body curve is greater thanthe distance threshold, the automatically determined vibrancy value maybe a pre-defined vibrancy value.

The lighting load may also or alternatively be configured in anadjustable vibrancy mode. When the adjustable vibrancy mode is enabled,the user may select a vibrancy value at which to control the light load.For example, the user may select the adjustable vibrancy value from arange of vibrancy values (e.g., 0 to 100). Increasing the vibrancy valuemay decrease the contribution of at least one the plurality of LEDswithin the lighting load (e.g., a white or substantially white LEDwithin the lighting load). Similarly, decreasing the adjustable vibrancyvalue may increase the contribution of at least one of the plurality ofLEDs.

As an example, a network device may include a display screen, acommunications circuit, and at least one processor. The network devicemay further include at least one tangible memory device communicativelycoupled to the at least one processor. The at least one tangible memorydevice may have software instructions stored thereon that when executedby the at least one processor may direct the at least one processor toreceive via the communications circuit from a communications networkinformation communicated by a controller.

The network device may be configured to define and/or control thevibrancy settings for a lighting load. The network device may beconfigured to display one or more graphical user interfaces that a userof the network device may interact with to define and/or update thevibrancy settings. For example, the graphical user interface displayedby the network device may include a palette for identifying a colorsetting for controlling the lighting load. The palette may be configuredto display different coordinated color temperature (CCT) values at whichthe plurality of LEDs of the lighting load are capable of beingcontrolled. The palette may also or alternatively be configured todisplay a color gamut of colors at which the plurality of LEDs of thelighting load are capable of being controlled.

The graphical user interface may also include a vibrancy controlinterface for identify the vibrancy settings of the lighting load. Forexample, the graphical user interface may include an actuator toindicate whether auto vibrancy mode is enabled. When the auto vibrancymode is selected, a vibrancy value may be automatically determinedvibrancy value based on the color setting selected via the palette.Further, as described herein, the automatically determined vibrancyvalue may be configured to emit light from the lighting load at or abovea target CRI value for the selected color setting.

The graphical user interface may include an actuator to indicate whetherthe adjustable vibrancy mode is enabled. When the adjustable vibrancymode is enabled, the graphical user interface may include a vibrancycontrol line for identifying a selection of the adjustable vibrancyvalue at which to control the light load. For example, the user may,using the vibrancy control line, select the adjustable vibrancy valuefrom a range of vibrancy values (e.g., 0 to 100). Increasing theadjustable vibrancy value using the vibrancy control line may decreasethe contribution of at least one the plurality of LEDs within thelighting load (e.g., a white or substantially white LED within thelighting load). Similarly, decreasing the adjustable vibrancy valueusing the vibrancy control line may increase the contribution of atleast one of the plurality of LEDs.

DETAILED DESCRIPTION

FIG. 1A shows a high-level diagram of an example load control system100. Load control system 100 may include a system controller 150 andload control devices for controlling (e.g., directly and/or indirectly)one or more electrical loads in a user environment 102 (also referred toherein as a load control environment). Example user environments/loadcontrol environments 102 may include one or more rooms of a home, one ormore floors of a building, one or more rooms of a hotel, etc. As anexample, load control system 100 may enable the automated control oflighting systems, shades, and heating, ventilating, and air conditioning(HVAC) systems in the user environment, among other electrical loads.

The load control devices of load control system 100 may include a systemcontroller 150, control-source devices (e.g., elements 108, 110, 120,and 122 discussed herein), and control-target devices (e.g., elements112, 113, 116, 124, and 126 discussed herein) (control-source devicesand control-target devices may be individually and/or collectivelyreferred to herein as load control devices and/or control devices). Thesystem controller 150, the control-source devices, and thecontrol-target devices may be configured to communicate (transmit and/orreceive) messages, such as digital messages (although other types ofmessages may be communicated), between one another using wirelesssignals 154 (e.g., radio-frequency (RF) signals), although wiredcommunications may also be used. “Digital” messages will be used hereinfor discussion purposes only.

The control-source devices may include, for example, input devices thatare configured to detect conditions within the user environment 102(e.g., user inputs via switches or keypads, occupancy/vacancyconditions, changes in measured light intensities, and/or other inputinformation) and in response to the detected conditions, transmitdigital messages to control-target devices that are configured tocontrol electrical loads in response to instructions or commandsreceived in the digital messages. The control-target devices mayinclude, for example, load control devices that are configured toreceive digital messages from the control-source devices and/or thesystem controller 150 and to control respective electrical loads inresponse to the received digital messages. A single control device ofthe load control system 100 may operate as both a control-source deviceand a control-target device.

According to one example, the system controller 150 may be configured toreceive the digital messages transmitted by the control-source devices,to interpret these messages based on system configuration data of theload control system, and to then transmit digital messages to thecontrol-target devices for the control-target devices to then controlrespective electrical loads. In other words, the control-source devicesand the control-target devices may communicate via the system controller150. According to another and/or additional example, the control-sourcedevices may directly communicate with the control-target devices withoutthe assistance of the system controller 150. The system controller maystill monitor such communications. According to a further and/oradditional example, the system controller 150 may originate and thencommunicate digital messages with control-source devices and/orcontrol-target devices. Such communications by the system controller 150may include programming/system configuration data (e.g., settings) forthe control devices, such as configuring scene buttons on lightswitches. Communications from the system controller 150 may alsoinclude, for example, messages directed to control-target devices andthat contain instructions or commands for the control-target devices tocontrol respective electrical loads in response to the receivedmessages. For example, the system controller 150 may communicatemessages to change light levels, to change shade levels, to change HVACsettings, etc. These are examples and other examples are possible.

Communications between the system controller 150, the control-sourcedevices, and the control-target devices may be via a wired and/orwireless communications network as indicated above. One example of awireless communications network may be a wireless LAN where the systemcontroller, control-source devices, and the control-target devices maycommunicate via a router, for example, that is local to the userenvironment 102. For example, such a network may be a standard Wi-Finetwork. Another example of a wireless communications network may be apoint-to-point communications network where the system controller,control-source devices, and the control-target devices communicatedirectly with one another using, for example, Bluetooth, Wi-Fi Direct, aproprietary communication channel, such as CLEAR CONNECT™, Thread,ZigBee, etc. to directly communicate. Other network configurations maybe used such as the system controller acting as an access point andproviding one or more wireless/wired based networks through which thesystem controller, the control-source devices, and the control-targetdevices may communicate.

For a control-target device to be responsive to messages from acontrol-source device, the control-source device may first be associatedwith the control-target device. As one example of an associationprocedure, a control-source device may be associated with acontrol-target device by a user 142 actuating a button on thecontrol-source device and/or the control-target device. The actuation ofthe button on the control-source device and/or the control-target devicemay place the control-source device and/or the control-target device inan association mode for being associated with one another. In theassociation mode, the control-source device may transmit an associationmessage(s) to the control-target device (directly or through the systemcontroller). The association message from the control-source device mayinclude a unique identifier of the control-source device. Thecontrol-target device may locally store the unique identifier of thecontrol-source, such that the control-target device may be capable ofrecognizing digital messages (e.g., subsequent digital messages) fromthe control-source device that may include load control instructions orcommands. The control-target device may be configured to respond to thedigital messages from the associated control-source device bycontrolling a corresponding electrical load according to the loadcontrol instructions received in the digital messages. This is merelyone example of how control devices may communicate and be associatedwith one another and other examples are possible. According to anotherexample, the system controller 150 may receive system configuration data(e.g., or subsequent updates to the system configuration data) from auser that specify which control-source devices should control whichcontrol-target devices. Thereafter, the system controller maycommunicate this system configuration data to the control-source devicesand/or control-target devices.

As one example of a control-target device, load control system 100 mayinclude one or more lighting control devices, such as the lightingcontrol devices 112 and 113. The lighting control device 112 may be adimmer, an electronic switch, a ballast, a light emitting diode (LED)driver(s), and/or the like. The lighting control device 112 may beconfigured to directly control an amount of power provided to a lightingload(s), such as lighting load 114. The lighting control device 112 maybe configured to wirelessly receive digital messages via signals 154(e.g., messages originating from a control-source device and/or thesystem controller 150), and to control the lighting load 114 in responseto the received digital messages. One will recognize that lightingcontrol device 112 and lighting load 114 may be integral and thus partof the same fixture or bulb, for example, or may be separate.

The lighting control device 113 may be a wall-mounted dimmer, awall-mounted switch, or other keypad device for controlling a lightingload(s), such as lighting load 115. The lighting control device 113 maybe adapted to be mounted in a standard electrical wall box. The lightingcontrol device 113 may include one or more buttons for controlling thelighting load 115. The lighting control device 113 may include a toggleactuator. Actuations (e.g., successive actuations) of the toggleactuator may toggle (e.g., turn off and on) the lighting load 115. Thelighting control device 113 may include an intensity adjustment actuator(e.g., a rocker switch or intensity adjustment buttons). Actuations ofan upper portion or a lower portion of the intensity adjustment actuatormay respectively increase or decrease the amount of power delivered tothe lighting load 115 and thus increase or decrease the intensity of thereceptive lighting load from a minimum intensity (e.g., approximately1%) to a maximum intensity (e.g., approximately 100%). The lightingcontrol device 113 may include a plurality (two or more) of visualindicators, e.g., light-emitting diodes (LEDs), which may be arranged ina linear array and that may illuminate to provide feedback of theintensity of the lighting load 115.

The lighting control device 113 may be configured to wirelessly receivedigital messages via wireless signals 154 (e.g., messages originatingfrom a control-source device and/or the system controller 150). Thelighting control device 113 may be configured to control the lightingload 115 in response to the received digital messages.

As described herein, a lighting control device, such as the lightingcontrol device 113 or 112 may control a lighting load (e.g., or aplurality of lighting loads), such as the lighting load 114 or 115,where the lighting load may include a plurality of multi-colored lightemitting diodes (LEDs). In other words, the lighting load may includewithin a single package, for example, a number of differently coloredemission LEDs and may be configured such that the chromaticity output ofthe LEDs is mixed to produce light having varying chromaticitycoordinates (e.g., color points) within a color gamut formed by thevarious LEDs that make up the lighting load (e.g., a total light outputfrom a lighting load that is made up of a plurality of LEDs). The CRIvalue may be a measurement of the white light emitted by the total lightoutput. The contribution or intensity of each of the differently coloredLEDs in emitting light may affect the CRI of the emitted light. Asdescribed herein, the CRI value of the light emitted from a given LED orthe lighting load comprising a plurality of LEDs may be a quantitativemeasurement of the emitted light's ability to reveal the colors ofvarious objects faithfully in comparison with an ideal or natural lightsource. Further, the CRI value of emitted light may be based on thespectrum emitted by the light. In some examples, the highest CRI valuemay be 100, which may indicate that the emitted light is identical(e.g., or substantially identical) to daylight (e.g., the combination ofdirect and indirect sunlight during the day). In certain instances, asfurther described herein, a lighting load may be configured to emitlight that achieves a CRI value is that at or above a target CRI value.

As one example, a lighting load may include one or more red LEDs, one ormore green LEDs, one or more blue LEDs, and one or more white, orsubstantially white LEDs (e.g., such as yellow and/or mint green LED(s))(which may be collectively referred to herein as a RGBW lighting load).Although the RGBW lighting load is described herein with a combinationof four LEDs of certain colors, other combinations of LEDs (e.g., moreor less LEDs and/or different color LEDs) may be used.

The lighting control device may adjust various settings of the lightingload(s) to adjust the light emitted from the lighting load. Theadjustments may be made in response to system configuration data. Thesystem configuration data may include control/configuration informationcomprising lighting control parameters (e.g., lighting intensitysettings, color settings, vibrancy setting, etc.) for controlling thelighting loads at the lighting control devices. For example, thelighting control device may adjust the lighting intensity settings(i.e., brightness), the color settings (e.g., CCT value or full colorvalue), vibrancy settings, CRI, etc., which are further describedherein. The lighting control devices may receive lighting controlparameters in the control/configuration information and control thecorresponding lighting load in response to the lighting controlparameters, for example, by generating control instructions based on thelighting control parameters and transmitting the control instructions tothe corresponding load. In certain example, the lighting control devicefor controlling a respective lighting load may be self-contained withinthe lighting load (e.g., the lighting control device and lighting loadexist within the same package, such as the lighting controldevice/lighting load 112/114). When the lighting control device andcorresponding lighting load are self-contained, the self-containedlighting control device (e.g., lighting control device/lighting load112/114) may itself receive the lighting control parameters, generatecontrol instructions, and control the lighting load.

The lighting control parameters may also, or alternatively, beassociated with a certain triggering event (e.g., a button press) andrespectively stored/maintained by the lighting control device. Then,when the lighting control device receives an indication of a certaintriggering event (e.g., an indication of a button press), the lightingcontrol device may retrieve or otherwise determine (e.g., by queryinganother device that stores/maintains the lighting control parameters)the lighting control parameters associated with that triggering event,and generate control instructions based on the lighting controlparameters and transmitting the control instructions to thecorresponding load. Also, or alternatively, when the lighting controldevice and corresponding lighting load are self-contained, theself-contained lighting control device (e.g., lighting controldevice/lighting load 112/114) may itself receive the lighting controlparameters, generate control instructions, and control the lightingload.

For example, the lighting control parameters may include a color setting(e.g., x-y chromaticity or CCT values), a lighting intensity settings,and/or a vibrancy settings (e.g., vibrancy mode and/or vibrancy value).

The light emitted from the lighting load(s) may result in a differentCRI value when different color settings, lighting intensities settings,and/or a vibrancy setting are selected. As further described herein,changes to the vibrancy settings may adjust the contribution of one ormore LEDs within a lighting load (e.g., adjust thecontribution/intensity ratio of the one or more LEDs), while maintainingthe selected color settings and lighting intensity setting. Further, thelighting control device may adjust the lighting control parameters oflighting load(s) over time (e.g., referred to herein as natural show ornatural lighting functionality). For example, the lighting controldevices may adjust the lighting control parameters of the lightingload(s) over time to emulate a sunrise and/or sunset, which, asdescribed herein, may be based on the local time of sunrise and/orsunset for the load control system/user environment.

A lighting control device and corresponding lighting load may beconfigured to produce a range of colors on a color gamut. The lightingcontrol device may produce a given color on the color gamut in responseto the color setting and/or lighting intensity settings received in thecontrol/configuration information. The color settings to which alighting control device may control a corresponding lighting load maydepend on the LEDs that make up the lighting load. For example, thelighting control device and the respective lighting load may beconfigured to produce white or near-white light of varyingbrightness/intensities within a range of correlated color temperatures(CCTs) on the black-body curve ranging from “warm white” (e.g., roughly2600 K-3000 K), to “neutral white” (e.g., 3000K-5000 K) to “cool white”(e.g., 5000 K-8300 K), for example (i.e., produce light of varyingchromaticity coordinates that lie along the black-body locus or curve).The white or near-white light may be produced by the lighting controldevice in response to the color setting being a CCT value, or inresponse to an x-y coordinate value on the color gamut. In certainsituations (e.g., as further described herein with respect to FIGS. 1Band 1C) a given x-y coordinate value on the color gamut may also equateto a corresponding CCT value, for example, when the given x-y coordinatevalue on the color gamut is close to or located on the black-body curve.As a further example, such a lighting control device and its respectivelighting load may be further configured to produce any of a plurality ofcolors of varying brightness/intensities within the color gamut formedby the various LEDs that make up the lighting load in response to thecolor setting and/or lighting intensity setting received in thecontrol/configuration information.

“Vibrancy,” as described herein, may be referred to as the ability totune the individual colors that make light at a given color (e.g., x-ychromaticity value or a CCT value). When vibrancy is adjusted, the colorof the light emitted by the lighting load may remain unchanged.Adjusting vibrancy may, however, adjust the light reflected off ofobjects in the space. Adjusting the vibrancy may further affect the CRIvalue of the light emitted by a lighting load. The effect that adjustingvibrancy has on the CRI value of the light emitted by a lighting loadmay, however, be based on the color (e.g., x-y chromaticity value or aCCT value) of the emitted light. For example, as the color of theemitted light diverges from the black-body curve, the ability toincrease the CRI value of the emitted light may decrease.

In addition, adjusting vibrancy may adjust spectral power distribution(SPD) of the light emitted by the lighting load. For example, asvibrancy increases, an SPD curve of the emitted light (e.g., relativeintensity vs wavelength) may change (e.g., the contributions of thenon-white colors may increase) and/or may result in individual colors onthe objects to appear more vibrant when the light reflects off of them.As described herein, increasing the vibrancy of a lighting load maydecrease the contribution or intensity of a white or substantially whiteLED within the lighting load, while increasing the contribution orintensity of the remaining LEDs within the lighting load (e.g., red,green, and blue LEDs). Taking, for example, an RGBW lighting load,increasing the vibrancy of the RGBW lighting load may decrease thecontribution/intensity of the white LED and increase the contribution ofthe red, green, and blue LEDs, while maintaining a given color settingwithin the color gamut. That is, increasing vibrancy increases thecontribution/intensity of red, blue, and green light in emitting lightat a given color, which, in turn allows an increased amount of red,blue, and green light to be reflected off of objects in a space, causingthe objects to be more vibrant. The vibrancy may be increased ordecreased, while maintaining the color and/or intensity being emitted bythe lighting load. In general, increasing the vibrancy of a RGBWlighting load may increase the intensity of one or more wavelengthsproduced by the red, green, and/or blue LEDs, for example, therebycausing certain objects within a space to look more “vibrant.”

The ability to adjust the vibrancy of a lighting load may be related tothe individual LEDs that are comprised within the lighting load. Asdescribed herein, for example, the chromaticity output of each of theseindividual LEDs within a lighting load may be mixed to produce lighthaving varying chromaticity coordinates (e.g., color points) within thecolor gamut formed by the plurality of LEDs. Further, the number and/orcolor of the LEDs included within a lighting load may determine how(e.g., the number of ways that) the lighting load can be controlled toemit light at a certain color (e.g., full color or CCT). That is,depending on the number and/or color of the LEDs within a light load,there may be multiple solutions for (e.g., multiple combinations of) theindividual chromaticity contributions of each of the LEDs within thelighting load to emit light at a given chromaticity coordinate. Since,as described herein, the vibrancy may be adjusted for a lighting loadwhile maintaining the color of the emitted light by changing the SPD ofthe emitted light (e.g., how the light reflects off of objects in thespace), the vibrancy of a lighting load may be adjusted using a numberof different solutions (e.g., combinations of intensities of differentLEDs in the lighting load), while emitting light at a given colorsetting. The effect that adjusting vibrancy has on a lighting load mayincrease as the number of solutions available for a lighting load (e.g.,combinations of intensities of different LEDs in the lighting load) toemit light at a given color increases. The number of solutions availablefor the lighting load (e.g., combinations of intensities of differentLEDs in the lighting load) to emit light at a given color may be aresult of the number and/or color of the LEDs included within thelighting load.

According to an example, a lighting control device and its respectivelighting load may be configured to one of two vibrancy modes, includingan auto vibrancy mode (e.g., a vibrancy value at which to control thelighting load is automatically determined based on the selected colorsettings, as described herein), and/or an adjustable vibrancy mode(e.g., the user may select an adjustable vibrancy level from a range ofvibrancy values). The selection of the various vibrancy modes may beincluded in the configuration/control information received by thelighting control device. The lighting control device may emit light at amixed color output based on the color setting and/or lighting intensitysetting received in the configuration/control information. Thechromaticity coordinates of the mixed color output of the lighting loadmay be the same (or approximately the same) across various vibrancyvalues. However, the intensities and/or contributions of the variousLEDs that make up a lighting load may be varied between various vibrancyvalues to maintain the selected color setting.

Taking, for example, an RGBW lighting load, as the color settingapproaches white light or color values on or near (e.g., within apredefined distance that equates to a color temperature value on) theblack-body curve, the lighting device may have a larger range (e.g., ornumber of solutions) of LED combinations (e.g., color and/or intensitycombinations) available for emitting light at the selected colorsetting. When the adjustable vibrancy or the auto vibrancy modes areenabled, the intensity of the white LED(s) for example, may be reduced(such as to 0%, for example) as compared to when the vibrancy value isset to 0, with the intensities of the remaining red, green, and/or blueLEDs adjusted to maintain the same color setting (or approximately thesame). As a result, the effect that configuring or controlling thevibrancy of a lighting load to different vibrancy values has on thelight emitted by the lighting load may increase as the selected colorsetting approaches white light or color values on or near the black-bodycurve. For example, the effect that changes in vibrancy has on the CRIvalue of the light emitted by the lighting load may decrease as thedistance between the selected color setting and the black-body curveincreases. As such, as the distance of the color from the black bodycurve increases, changes in the vibrancy value may have less of aneffect or fail to change the CRI value, and may fail by enough to reachor come close to the target CRI value that is set for colors that are onor near the black body curve. In addition, as the distance of the colorfrom the black body curve increases, the relevancy of the CRI value ofthe emitted light may decrease (e.g., as the CRI value of the light ismore relevant when the light is white or near white light, such as lightthat is near the black-body curve.

It should, however, be recognized that controlling the vibrancy of agiven lighting load depends on the lighting load itself (e.g., theindividual LEDs within the lighting load). That is, the effect thatchanges in the vibrancy has on the CRI of the light emitted by thelighting load depends on the individual LEDs within the lighting load(e.g., the color, intensity, etc. of the individual LEDs within thelighting load). Changes in the vibrancy value may have a greater effecton the CRI of the light emitted by the lighting load as the selectedcolor nears the black body curve. Similarly, changes in the vibrancyvalue may have less of an effect on the CRI of the light emitted by thelighting load as the selected color is further from the black bodycurve. Though the range of vibrancy values available at a given colormay vary as colors are selected on the color gamut, the target CRI valuethat is set for being achieved at or within a predefined distance of theblack body curve may be unable to be achieved at colors that areselected outside of the predefined distance of the black body curve.

Again, according to one example, the difference between given vibrancyvalues may be the intensity setting of the white LED(s)/the amount thewhite LED(s) (e.g., or other LEDs) contribute to the mixed color outputof the lighting load, with the white LED(s) contributing less when thevibrancy value is higher. Similarly, the white LED(s) may contributemore when the vibrancy value is lower. Other examples are also possible.An example of such a lighting control device and respective lightingload is described as an illumination device, as described in U.S. PatentApplication Publication Number 2018/0077770, the contents of which arehereby incorporated by reference in their entirety. One will recognizethat other examples lighting control device and respective lightingloads are possible.

As described herein, the light output of a lighting load and/or thelight output of the individual LEDs within the lighting load may bemeasured by a CRI value. The CRI value may be a measurement of thelighting load's ability to reveal the actual color of objects ascompared to an ideal light source (e.g., a natural light source, such asthe sun). A higher CRI value may be a desirable characteristic of auser. For example, a lighting load with a higher CRI value may providelight such that the objects within a space reflect light at a naturalcolor. A lighting load itself may be defined by a CRI value. CRI valuesmay be in the range of 0 to 100, inclusively. For example, the lowestCRI value may be 0 and the highest CRI value may be 100.

The CRI value for a given color may change in response to changes in thevibrancy value used to control the lighting control device. For example,the lighting control device may control a respective lighting load to acolor setting and/or intensity level that is received incontrol/configuration information. As described herein, a given colorsetting and/or lighting intensity setting may have a correspondingvibrancy value to which the lighting control device may be controlledwhen the auto vibrancy mode is enabled. In response to changes in thevibrancy value for a given color setting, the light emitted from thelighting load may have a different corresponding CRI value. As a result,when the auto vibrancy mode is enabled a vibrancy value may beautomatically determined (e.g., by a control/configuration application)to emit light from the lighting load at a CRI value that is at or abovea target CRI value for the selected color setting. The effect that theautomatically determined vibrancy value has on the CRI value of thelight emitted by the lighting load may, however, be based on theselected color setting. For example, the effect that the automaticallydetermined vibrancy value has on the CRI value of the light emitted bythe lighting load may increase as the selected color setting approachesthe black-body curve. That is, in an auto vibrancy mode, the CRI valueof the light emitted from a lighting load may be higher as the selectedcolor setting approaches the black-body curve. Similarly, in an autovibrancy mode, the CRI value of the light emitted from a lighting loadmay be lower (e.g., the highest achievable CRI value may be lower) asthe selected color setting is further from the black-body curve and/orapproaches more saturated colors. Accordingly, as the selected colorsetting diverges from the black-body curve (e.g., the distance betweenthe selected color setting and the black-body curve increases), the CRIvalue of the emitted light that results from the automaticallydetermined vibrancy value when the auto vibrancy mode is enabled maydecrease. Thus, the target CRI value that is set for when the colorsetting is on or within a predefined distance of the black body curvemay be unable to be achieved at other color settings (e.g., moresaturated colors).

In auto vibrancy mode, a control/configuration application, as describedherein (e.g., a control/configuration application running on a networkdevice), may be used to automatically determine a vibrancy value to emitlight from one or more lighting loads at a CRI value, that is greaterthan or equal to a target CRI value. A CRI value greater than or equalto a target CRI value (e.g., a CRI value of 90) may be desirable and maybe referred to herein as “optimal,” “optimized,” or “maximized.” Thatsaid, other ranges (e.g., smaller and/or larger ranges) may also beconsidered “optimal,” “optimized,” or “maximized.”

When auto vibrancy mode is selected, the lighting load may be configuredto an automatically determined vibrancy value so that the lighting loademits light at a CRI value that is greater than or equal to a target CRIvalue. As the target CRI value may be unable to be achieved for theselected color setting (e.g., due to the selected color setting beingtoo far from the black-body curve), the vibrancy value that results inthe highest CRI value toward the target CRI value may be selected. Incertain instances, for example, when auto vibrancy mode is selected, theCRI value of a lighting load may be increased to a value greater than orequal to a target CRI value. For example, the target CRI value may be90. One will appreciate, however, that the target CRI value may be othervalues. That is, the target CRI value may be a value which may beconsidered a desirable threshold that a system may attempt to achievegiven the certain characteristics of the load control system and/orlighting control devices (e.g., quality, color, and number of the LEDsused in a lighting load). The vibrancy value may be automaticallydetermined to increase the CRI value to a value that is toward thetarget CRI value. If a greater CRI value is available, the vibrancyvalue may be increased until a highest available CRI value is obtainedfor the selected color setting. As described herein, optimizing the CRIvalue towards or above the target CRI value may be referred to asoptimizing the CRI value. This feature may be enabled through the autovibrancy mode.

As described herein, the vibrancy settings (e.g., vibrancy mode and/orvibrancy values), which, as described herein, may be used to control theCRI of the emitted light, for a lighting load that comprises a pluralityof LEDs (e.g., an RGBW lighting load) may be configured via acontrol/configuration application. For example, the lighting load may beset to an auto vibrancy mode, wherein a vibrancy value may beautomatically determined, for example, by the control/configurationapplication. The lighting load may alternatively be set to an adjustablevibrancy mode, wherein an adjustable vibrancy value for the lightingload is selected by a user.

Referring first to the auto vibrancy mode, the automatically determinedvibrancy value may be based on a distance that the selected colorsetting for the lighting load is from the black-body curve on the colorspectrum (e.g., or another predefined range of color values on the colorspectrum). For example, as the selected color setting nears white lightor the black-body curve, the automatically determined vibrancy value mayincrease as the selected color approaches white light or the black-bodycurve (e.g., in an attempt to increase the CRI value of the light beingemitted from the lighting load). Further, since certain x-y chromaticityvalues may be close enough to the black-body curve to have an equivalentCCT value, the distance the selected color setting for a lighting loadis from the black-body curve may indicate whether a certain colorsetting has an equivalent CCT value. Accordingly, if the distance thatthe selected color setting for the lighting load is from the black-bodycurve on the color spectrum is less than a distance threshold, theselected color setting may be considered to have an equivalent CCT valueon the black-body curve. Further, the automatically determined vibrancyvalue for the selected color setting with a distance that is less thanthe distance threshold may be the same as the automatically determinedvibrancy value for the equivalent CCT value of the selected colorsetting.

The effect that changes in vibrancy has on the CRI value of the lightemitted by the lighting load may decrease as the distance between theselected color setting and the black-body curve increases. As a result,the automatically determined vibrancy value may be automaticallyselected to optimize CRI when the color setting is on, or within apredefined distance to have an equivalent value to, the black bodycurve. As the selected color setting diverges from the black-body curve(e.g., the distance between the selected color setting and theblack-body curve increases), however, the effect of the automaticallydetermined vibrancy value on the CRI value of the emitted light maydecrease. The automatically determined vibrancy value may result in theemission of light from the lighting load approaching, at, or above thetarget CRI value when the selected color setting is within a predefineddistance from the black-body curve.

It should be appreciated, however, that the effect the automaticallydetermined vibrancy value has on a given lighting load may depend on theindividual LEDs that make up the lighting load. That is, anautomatically determined vibrancy value that results in the emission oflight from the lighting load at or above a target CRI value may dependon the individual LEDs that are within the lighting load. Putdifferently, an automatically determined vibrancy value that results inthe emission of light from a first lighting load at or above a targetCRI value may differ from an automatically determined vibrancy valuethat results in the emission of light from a second lighting load at orabove a target CRI value (e.g., based on the individual LEDs within eachof the lighting loads). Though the vibrancy value may be different for adifferent lighting load comprising different LEDs, as the target CRIvalue may change for optimizing CRI, the vibrancy value may similarlyincrease as the color temperature value of the color setting increasesto optimize CRI.

FIG. 1B illustrates an example color gamut 200. For example, the colorgamut 200 may illustrate the color spectrum of colors that may be formedby the various LEDs that make up a lighting load (e.g., a RGBW lighting)load. The color gamut 200 may further include a black-body curve 201. Asdescribed herein, the black-body curve 201 may illustrate the locationof white or near-white light of varying brightness/intensities withinthe color gamut 200. The black-body curve 201 may further be identifiedby a range of correlated color temperatures (CCTs), ranging from “warmwhite” (e.g., roughly 2600 K-3000 K), to “neutral white” (e.g., 3000K-5000 K) to “cool white” (e.g., 5000 K-8300 K), for example. Asdescribed herein, adjusting the vibrancy of a lighting load may includeadjusting the contribution of a white or substantially white LEDincluded within the lighting load. Therefore, the effect that a givenvibrancy value of a lighting load has on the CRI value of the lightemitted by the light emitted by the lighting load may increase as theselected color approaches the black-body curve 201 (e.g., whichillustrates the location of white or near-white light within the colorgamut 200).

As described herein, however, the effect that a vibrancy value has on agiven lighting load may depend on the individual LEDs that make up thelighting load. As a result, the effect that the vibrancy value has onthe CRI value of the light emitted by the lighting load may also dependon the individual LEDs that make up the lighting load. Therefore, incertain situations (e.g., depending on the individual LEDs that make upa lighting load), the effect of configuring or tuning the vibrancy valueof a lighting load may increase as the selected color approaches theoutput of a white or substantially white LED (e.g., a mint green LED)within the lighting load and/or as the number of differently coloredLEDs within the lighting load increases.

Referring back to FIG. 1B, the color setting 205, may be selected as theconfigured color value for a lighting load. For example, the colorsetting 205 may be a light yellow color having approximate x-ychromaticity components of (0.35, 0.31). As described herein, when autovibrancy mode is enabled for a lighting load configured to the colorsetting 205, a vibrancy level may be automatically determined based on adistance 207 between the selected color setting 205 and the black-bodycurve 201 (e.g., or another predefined range of color values on thecolor gamut 201). Further, the automatically determined vibrancy valuemay result in the emission of light from the lighting load at a CRIvalue that is at or above the target CRI value. However, as describedherein, the effect that the automatically determined vibrancy value of alighting load has on the CRI value of the light emitted by the lightingload may decrease as the selected color setting diverges from theblack-body curve 201.

The distance 207 may indicate whether the color setting 205 has anequivalent CCT value on the black-body curve 201. If, for example, thedistance 207 is less than a distance threshold (e.g., indicating thatthe color setting 205 has an equivalent CCT value), the automaticallydetermined vibrancy value may be the automatically determined vibrancythat results in the emission of light from the lighting load at or abovethe target CRI value for the equivalent CCT value. When the target CRIvalue is unable to be reached for the color setting, the vibrancy may beautomatically determined such that the CRI value approaches the targetCRI, such that the highest CRI value is achieved for the selected colorsetting. Further, as described herein, the effect that tuning orconfiguring the vibrancy value of a lighting load has on the lightemitted by the lighting load (e.g., the CRI value of the light emittedby the lighting load) may decrease as the distance between the selectedcolor setting 205 and the black-body curve 201 increases. As a result,if, for example, the distance 207 between the selected color setting 205and the black-body curve 201 is greater than the distance threshold, theautomatically determined vibrancy value may be set to a predefinedvalue.

Referring again to FIG. 1B, the effect that tuning or configuring thevibrancy value of a lighting load has on the light emitted by thelighting load (e.g., the CRI value of the light emitted by the lightingload) may peak when the selected color setting is on (e.g., orsubstantially near) the black-body curve 201. As a result, when autovibrancy is enabled for a lighting load that is configured to a colorsetting on (e.g., or substantially near) the black-body curve 201, theautomatically determined vibrancy value may correspond to a predefinedvibrancy value that maximizes CRI at or above the target CRI value. Inaddition, the automatically determined vibrancy value may increase(e.g., the contribution/intensity of a white or substantially white LEDin an RGBW lighting load decreases) as the selected color setting (e.g.,CCT value) increases to achieve a target CRI value.

Table 1, reproduced below, illustrates example vibrancy values that maybe automatically determined for certain color settings (e.g., CCTvalues), for example, when auto vibrancy mode is enabled. As shown inTable 1, the automatically determined vibrancy value may increase as theselected CCT value increases. And, as described herein, the increasedvibrancy values may decrease the contribution of at least one of theplurality of LEDs within the lighting load (e.g., the white orsubstantially white LED). The automatically determined vibrancy valuemay also be configured to emit light at or above a target CRI value,which, as described herein, may vary based on the selected colorsettings.

TABLE 1 Automatically Determined CCT Value Vibrancy Value CRI Value2700K 25 92.1 3000K 27 92.6 3500K 29 91.8 4000K 35 91.3 5000K 41 90.26500K 44 89.7

A lighting load may also be set to an adjustable vibrancy mode, which,as described herein, may allow a user to select a given vibrancy value.For example, the adjustable vibrancy value may be selected from a rangeof vibrancy values (e.g., 0 to 100). As the adjustable vibrancy valueincreases, the contribution of at least one of the plurality of LEDs inthe lighting load (e.g., the white or substantially white LED) maydecrease. Accordingly, the effect that configuring or controlling thevibrancy settings (e.g., vibrancy mode and/or vibrancy value) has on thelight emitted by the lighting load may decrease as the distance betweenthe selected color setting and the black-body curve increases (e.g., isgreater than a distance threshold). Referring again to FIG. 1B, as theselected color diverges from (e.g., the distance between increases) theblack-body curve 201, the effect that configuring or controlling thevibrancy settings (e.g., vibrancy mode and/or vibrancy value) has on thelight emitted by the lighting load. As a result, as the selected colordiverges from (e.g., the distance between increases) the black-bodycurve 201, the effect that the automatically determined vibrancy valuein the auto vibrancy mode has on the light emitted by the lighting loadmay decrease (e.g., the CRI value of the emitted light may be unable toachieve the target CRI). For example, in certain situations (e.g., whenthe color setting is substantially far from the black-body curve 201)the vibrancy settings may bet set to default values.

FIG. 1C illustrates another example color gamut 200 a. The color gamut200 a may illustrate a subset of the color gamut 200 that focuses on theblack-body curve 201. Further, the color gamut 200 a may furtherillustrate the x-y chromaticity values that have equivalent CCT valueson the black-body curve 201. Referring back to FIG. 1C, the color gamut200 a may include a plurality of CCT equivalency areas 282 a-h. Each ofthe CCT equivalency areas 282 a-h may define the x-y chromaticity valuesthat may have an equivalent CCT value on the black-body curve 201. Putanother way, each of the CCT equivalency areas 282 a-h may illustratethe distance 207 referenced in FIG. 1B that a given color setting may befrom the black-body curve 201 to have an equivalent CCT value on theblack-body curve 201.

Each of the CCT value equivalency areas 282 a-h may indicate the areas(e.g., or quadrangles) of x-y chromaticity values around a specific CCTvalue on the black-body curve 201 that may be equivalent to thatspecific CCT value. That is, the x-y chromaticity values that fallwithin the CCT value equivalency area for a given CCT value may beequivalent to that CCT value. For example, the CCT equivalency area 282a may include the x-y chromaticity values that are equivalent to a CCTvalue of 6500 K, Similarly, the CCT value equivalency area 282 h mayinclude the x-y chromaticity values that are equivalent to a CCT value2700 K. Further, as shown in in FIG. 1C, CCT value equivalency areas mayincrease (e.g., the area of equivalent x-y chromaticity values thatsurround a given CCT value may increase) as the respective CCT valuesincrease along the black-body curve 201.

A user may configure or control certain values for the settingsdescribed herein (e.g., lighting intensity settings, color settings,vibrancy settings, etc.) for one or more lighting loads and save thesettings to a defined scene. For example, as described herein, a usermay configure or control certain values for the settings saved to adefined scene by interaction with one or more graphical user interfacesthat may be displayed by a control/configuration application. The usermay configure the scene to control one more lighting loads, for example,by assigning the scene to control a zone that the one more lightingloads are assigned to. The scene may also be associated with a button ona remote control device or keypad, and the scene may be enabled oractivated when the button is pressed. When a scene is activated, one ormore messages that include one or more parameters for controlling thelighting loads in accordance with the scene may be transmitted.

A user may also configure or control the values for the settingsdescribed herein (e.g., lighting intensity settings, color settings,vibrancy settings, etc.) to change over time, which is referred toherein as natural show or natural lighting functionality. For example,the settings of a lighting load may be configured to change over timeand emulate sunrise and/or sunset. Similarly, as described in moredetail with respect to FIG. 5A, the vibrancy settings (e.g., vibrancymode and/or vibrancy value) of a lighting load may be configured tochange over time, for example, such that the light reflected off ofobjects in the space appear more vibrant over time. Again, a user maychange or update the settings of a natural show or natural lightingfunctionality, for example, via a network device. For example, asdescribed herein, a control/configuration application of the networkdevice may display one or more graphical user interface, and the usermay interact with the graphical user interface to make changes orupdates the natural show settings. After being configured, natural showfunctionality may be assigned to and/or enabled by a scene (e.g., bypressing a button that enables the scene). Also, or alternatively,natural show functionality may be enabled based on a schedule or inresponse to the detection of an event, such as an occupancy sensordetecting occupancy.

The load control system 100 may include one or more other control-targetdevices, such as a motorized window treatment 116 for directlycontrolling the covering material 118 (e.g., via an electrical motor);ceiling fans; a table top or plug-in load control device 126 fordirectly controlling a floor lamp 128, a desk lamp, and/or otherelectrical loads that may be plugged into the plug-in load controldevice 126; and/or a temperature control device 124 (e.g., thermostat)for directly controlling an HVAC system (not shown). The load controlsystem 100 may also, or alternatively, include an audio control device(e.g., a speaker system) and/or a video control device (e.g., a devicecapable of streaming video content). Again, these devices may beconfigured to wirelessly receive digital messages via wireless signals154 (e.g., messages originating from a control-source device and/or thesystem controller 150). These devices may be configured to controlrespective electrical loads in response to the received digitalmessages.

Control-target devices, in addition to being configured to wirelesslyreceive digital messages via wireless signals and to control respectiveelectrical loads in response to the received digital messages, may alsobe configured to wirelessly transmit digital messages via wirelesssignals (e.g., to the system controller 150 and/or an associated controldevice(s)). A control-target device may communicate such messages toconfirm receipt of messages and actions taken, to report status (e.g.,light levels), etc. Again, control-target devices may also oralternatively communicate via wired communications.

With respect to control-source devices, the load control system 100 mayinclude one or more remote-control devices 122, one or more occupancysensors 110, one or more daylight sensors 108, and/or one or more windowsensors 120. The control-source devices may wirelessly send orcommunicate digital messages via wireless signals, such as signals 154,to associated control-target devices (e.g., directly or via the systemcontroller) for controlling an electrical load. The remote-controldevice 122 may send digital messages for controlling one or morecontrol-target devices after actuation of one or more buttons on theremote-control device 122. For example, the remote control device 122may be a keypad. One or more buttons on the control device 122 maycorrespond to a preset scene for controlling the lighting load 115 or112/114, for example. For example, the buttons on the control device 122may be pre-configured to correspond to a preset scene for controllingthe lighting load 115 or 112/114. The occupancy sensor 110 may senddigital messages to control-target devices in response to an occupancyand/or vacancy condition (e.g., movement or lack of movement) that issensed within its observable area. The daylight sensor 108 may senddigital messages to control-target devices in response to the detectionof an amount of light within its observable area. The window sensor 120may send digital messages to control-target devices in response to ameasured level of light received from outside of the user environment102. For example, the window sensor 120 may detect when sunlight isdirectly shining into the window sensor 120, is reflected onto thewindow sensor 120, and/or is blocked by external means, such as cloudsor a building. The window sensor 120 may send digital messagesindicating the measured light level. The load control system 100 mayinclude one or more other control-source devices. Again, one willrecognize that control-source devices may also or alternativelycommunicate via wired communications.

Turning again to the system controller 150, it may facilitate thecommunication of messages from control-source devices to associatedcontrol-target devices and/or monitor such messages as indicated above,thereby knowing when a control-source device detects an event and when acontrol-target device is changing the status/state of an electricalload. The system controller 150 may communicate programming/systemconfiguration data to the control devices. The system controller 150 mayalso be the source of control messages to control-target devices, forexample, instructing the devices to control corresponding electricalloads. As one example of the later, the system controller 150 may runone or more time-clock operations that automatically communicatesmessages to control-target devices based on configured schedules (e.g.,commands to lighting control device 113 to adjust lighting load 115,commands to lighting control device 112 to adjust lighting load 115,commands to motorized window treatment 116 for directly controlling thecovering material 118, etc.) For description purposes, shades will beused herein to describe functions and features related to motorizedwindow treatments. Nonetheless, one will recognize that features andfunctions described herein are applicable to other types of windowcoverings such as drapes, curtains, blinds, etc. Other examples arepossible.

According to a further aspect of load control system 100, the systemcontroller 150 may be configured to communicate with one or more networkdevices 144 in use by a user(s) 142, for example. The network device 144may include a personal computer (PC), a laptop, a tablet, a smart phone,or another electronic computing device (e.g., a cloud computing device).In addition, the network device may be a device local to the loadcontrol system 100 (e.g., as illustrated in FIG. 1 ) or as an externaldevice (e.g., accessed via the cloud). The system controller 150 and thenetwork device 144 may communicate via a wired and/or wirelesscommunications network. The communications network may be the samenetwork used by the system controller 150 and the control devices, ormay be a different network (e.g., a wireless communications networkusing wireless signals 152). As one example, the system controller 150and the network device 144 may communicate over a wireless LAN (e.g.,that is local to the user environment 102). For example, such a networkmay be a standard Wi-Fi network provided by a router local to the userenvironment 102. As another example, the system controller 150 and thenetwork device 144 may communicate directly with one-another using, forexample, Bluetooth, Wi-Fi Direct, etc. Other examples are possible suchas the system controller acting as an access point and providing one ormore wireless/wired based networks through which the system controllerand network device may communicate.

The load control system 100 of FIG. 1A may be configured such that thesystem controller 150 is capable of communicating with a network device144 when that device is local to the system controller 150, e.g., forthe network device 144 and system controller 150 to directly communicatein a point-to-point fashion or through a local network specific to theuser environment 102 (e.g., such as a network provided by a router thatis local to the user environment). For example, a user of network device144 may communicate with the system controller 150 to control the loadcontrol system 100 from remote locations, such as via the Internet orother public or private network. Similarly, third-party integrators mayalso communicate with the system controller 150, for example, in orderto provide enhanced services to users of user environment 102. Forexample, a third-party integrator may provide other systems within userenvironment 102. It may be beneficial to integrate such systems withload control system 100. Accordingly, the network device 144 may beconfigured to allow the user 142 to configure or control the loadcontrol system 100.

As described herein, the system controller 150 may be configured tocommunicate with one or more network devices 144 in use by a user(s)142. The network device 144 may include a personal computer (PC), alaptop, a tablet, a smart phone, or In addition, the network device 144may be a device local to the load control system 100 (e.g., asillustrated in FIG. 1 ) or The system controller 150 and the networkdevice 144 may communicate via a wired and/or wireless communicationsnetwork. The communications network may be the same network used by thesystem controller 150 and the control devices, or may be a differentnetwork (e.g., a wireless communications network using wireless signals152). As one example, the system controller 150 and the network device144 may communicate over a wireless LAN (e.g., that is local to the userenvironment 102). For example, such a network may be a standard Wi-Finetwork provided by a router local to the user environment 102. Asanother example, the system controller 150 and the network device 144may communicate directly with one-another using, for example, Bluetooth,Wi-Fi Direct, etc. Other examples are possible such as the systemcontroller acting as an access point and providing one or morewireless/wired based networks through which the system controller andnetwork device may communicate.

In general, the system controller 150 may be configured to allow a user142 of the network device 144 to determine, for example, the systemconfiguration data for the user environment 102 and load control system100, such as rooms in the environment, which control devices are inwhich rooms (e.g., the location of the control devices within the userenvironment, such as which rooms), to determine the status and/orcontrol/configuration information of control devices (e.g., lightingintensity settings, color settings, vibrancy settings, HVAC levels,shade levels), to configure the system controller (e.g., to change timeclock schedules), to issue commands to the system controller in order tocontrol and/or configure the control devices (e.g., change light levels,change HVAC levels, change shade levels, change presets, etc.), etc.Other examples are possible as described herein.

The network device 144 may include a control/configuration applicationfor generating and/or compiling the intended system configuration datafor the user environment 102 and load control system 100, as furtherdescribed herein. The control/configuration application may be used togenerate system configuration data, for example, via the user providinginputs and/or configuration information to the control/configurationapplication. After generating the system configuration data and/orupdating the system configuration data, the network device 144, via thecontrol/configuration application, may transmit the system configurationdata (e.g., or any updates) to other devices in the load control system100 (e.g., the system controller 150, remote-control device 122, controltarget devices, etc.). Then, in response to a triggering event (e.g.,enabling a scene, enabling natural light, a sensor event, etc.), forexample, one or more devices may perform control based on the systemconfiguration data.

System configuration data may include information about the devices in auser environment or load control system. For example, systemconfiguration data may include the location of the devices within theload control system or user environment (e.g., a text string thatrepresent a device's location) and/or if the device is assigned to acertain zone. In addition, the system configuration data may includecontrol/configuration information that defines lighting controlparameters. For example, the control/configuration information maydefine the scenes of the load control system, the respective lightingcontrol parameters for each of the defined scenes (e.g., lightingintensity settings, vibrancy settings, color settings, etc.), and/or thebuttons that may be pressed to enable each of the defined scenes. Thesystem configuration data may also include control/configurationinformation for the natural show or natural lighting functionality(e.g., changes in the lighting control parameters over time) defined forthe load control system. The system configuration data may includeadditional information about the devices in the user environment or loadcontrol system, and the examples provided herein are not exhaustive. Thesystem configuration data may include any configuration information thatmay be used to configure or control a user environment or load controlsystem (e.g., one or more of a unique identifiers of a device, a list ofassociated devices, a zone identifier, a scene identifier, etc.).

The load control system 100 of FIG. 1A may be configured such that thesystem controller 150 is capable of communicating with a network device144 when that device is local to the system controller, in other words,for the two to directly communicate in a point-to-point fashion orthrough a local network specific to the user environment 102 (such as anetwork provided by a router that is local to the user environment). Itmay be advantageous to allow a user of network device 144 to communicatewith the system controller 150 and to control the load control system100 from remote locations, such as via the Internet or other public orprivate network. Similarly, it may be advantageous to allow third-partyintegrators to communicate with the system controller 150 in order toprovide enhanced services to users of user environment 102. For example,a third-party integrator may provide other systems within userenvironment 102. It may be beneficial to integrate such systems withload control system 100.

FIG. 2 shows an example block diagram of network device 280 (thisdiagram may also apply to the network devices 144 or a remote networkdevice, for example). Network device 280 may include one or more generalpurpose processors, special purpose processors, conventional processors,digital signal processors (DSPs), microprocessors, microcontrollers,integrated circuits, programmable logic devices (PLD), applicationspecific integrated circuits (ASICs), or the like and/or may furtherinclude other processing element(s) such as one or more graphicprocessors (hereinafter collectively referred to as control circuits(s)202). Control circuit(s) 202 may control the functionality of thenetwork device and may execute the control/configuration application203, in addition to other software applications such an operatingsystem(s), database management systems, etc., to provide features andfunctions as describe herein. The control circuit(s) 202 may alsoperform signal coding, data processing, power control, input/outputprocessing, and any other functionality that enables the network device280 to perform as described herein. The network device 280 may alsoinclude one or more memory 204 (including volatile and non-volatilememory) which may be non-removable memory and/or a removable memory.

Memory 204 may be communicatively coupled to the control circuit(s) 202.Non-removable memory 204 may include random-access memory (RAM),read-only memory (ROM), a hard disk(s), or any other type ofnon-removable memory storage. Removable memory 204 may include asubscriber identity module (SIM) card, a memory stick, a memory card, orany other type of removable memory. The one or more memory 204 may storethe control/configuration application 203 and may also provide anexecution space as the processor(s) execute the control/configurationapplication. Network device 280 may also include a visual displayscreen(s)/terminal(s) 206 that may be communicatively coupled to thecontrol circuit(s) 202. Together with control circuit(s) 202, visualdisplay screen(s) 206 may display information to the user via one ormore GUI based interfaces/GUI based “window(s)” as described herein. Thedisplay screen(s) 206 and the control circuit(s) 202 may be in two-waycommunication, as the display screen 206 may include a touch sensitivevisual screen component configured to receive information from a userand providing such information to the control circuit(s) 202

Network device 280 may also include one or more input/output (I/O)devices 212 (e.g., a keyboard, a touch sensitive pad, a mouse, atrackball, audio speaker, audio receiver, etc.) that may becommunicatively coupled to the control circuit(s) 202. The I/O devicesmay allow the user to interact with the control/configurationapplication 203, for example. Network device 280 may further include oneor more transceivers/communications circuits (collectively,communications circuit(s) 208) for communicating (transmitting and/orreceiving) over wired and/or wireless communication networks, forexample. The communications circuit(s) 208 may include an RFtransceiver(s) or other circuit(s) configured to perform wirelesscommunications via an antenna(s). Communications circuit(s) 208 may bein communication with control circuit(s) 202 for transmitting and/orreceiving information. Each of the components within the network device280 may be powered by a power source 210. The power source 210 mayinclude an AC power supply and/or DC power supply, for example. Thepower source 210 may generate a supply voltage(s) V_(CC) for poweringthe components within the network device 280.

In addition to including GUI based software components, for example,that provide the graphical features and visual images described herein,the control/configuration application 203 may also include a logicengine(s) for providing features of the GUI and features of theapplication in general as described herein. The GUI based softwarecomponents and/or logic engine may be one or more software basedcomponents that include instructions, for example, that are stored onand/or execute from one or more tangible memory devices/components ofthe network device as indicated above. Features of thecontrol/configuration application may also and/or alternatively beprovided by firmware and/or hardware in addition to/as an alternative tosoftware based components. Again, network device 280 is an example andthe control/configuration application may execute on other types ofcomputing devices.

As indicted, network device 280 may be similar to the network device 144(e.g., including an external network device accessed via a cloud), asdescribed herein. Accordingly, the control/configuration application maycommunicate with the other devices of the user environment (e.g., thesystem controller, control-source devices, control-target devices etc.)via a network local to the user environment (such as a Wi-Fi network).Nonetheless, one will recognize that the control/configurationapplication 203/network device 280 may communicate with other devicesusing other communication systems and/or protocols, etc. In addition,the control/configuration application 203 is described herein as being aself-contained application that executes on the network device 280 andcommunicates messages with the system controller, for example. In otherwords, logic of the control/configuration application and generatedgraphics associated with the application are described herein asexecuting from the network device. Nonetheless, features and/or graphicsof the control/configuration application may be implemented in otherfashions, such as a web hosted application with the network deviceinterfacing with the web hosted application using a local application(e.g., a web browser or other application) for providing features andfunctions as described herein. As one example, the system controller mayfunction as the web host.

In general, while a user environment may include control devices thatthe control/configuration application/network device 280 may interactwith, control, and/or configure via a system controller (e.g., thesystem controller 150), the user environment may also include othertypes of control devices that may be, for example, Wi-Fi enabled and/orinternet of things enabled control devices for example (e.g., devicesthat are configured to communicate via wireless and/or wired basednetworks, such as HomeKit). For description purposes, such other controldevices (e.g., control devices to which the control/configurationapplication and/or network device 280 does not communicate with via thesystem controller) may be referred to herein as Wi-Fi enabled and/orHomeKit enabled control devices. Nonetheless, one will recognize thatthe features described herein are not limited to Wi-Fi enabled and/orHomeKit enabled control devices. Examples of such other control devicesmay include lighting control devices/bulbs, thermostats, fans, etc.

Network device 280 and the Wi-Fi enabled control devices, for example,may be configured to directly communicate with each other without havingto communicate through a system controller (e.g., if the network deviceis also HomeKit enabled), and/or may communicate via one or more cloudbased servers, for example, again without communicating through thesystem controller. According to one aspect of the control/configurationapplication 203 described herein, assuming the network device 280 isconfigured to communicate with such Wi-Fi enabled control devices (e.g.,via HomeKit), for example, the control/configuration application may beconfigured to also interact with, control, and/or configure thesedevices, in addition to control devices. In so doing, thecontrol/configuration application may combine within the graphicalinterfaces described herein information obtained from such Wi-Fi enableddevices, for example, and information obtained on control devices thatare controlled by the system controller.

The control/configuration application 203 may also provide interfacesthat allow a user to control and/or configure both Wi-Fi enabled controldevices, for example, and control devices that are controlled by thesystem controller. For ease of description, the control/configurationapplication 203 will be described herein as interacting with controldevices of a load control system. Nonetheless, similar functionality asdescribed herein may also apply to Wi-Fi enabled devices that may not becontrolled via the system controller and to which the network device maydirectly and/or indirectly communicate. One will also recognize that thecontrol/configuration application described herein may alternativelycontrol Wi-Fi enabled devices, for example, with which the networkdevice 280 is configured to directly and/or indirectly control/interactwith. Again, one will further recognize that while control/configurationapplication 203 is described herein in the context of a load controlsystem and communication systems, the features and functions of thecontrol/configuration application are applicable to other types ofcontrol devices, load control systems, and communication systemsincluding for example, Wi-Fi enabled and/or HomeKit enabled systems

As one example, the network device 280 may display to a user via avisual display screen 206 an icon associated with thecontrol/configuration application 203. The network device 280 may detectthe selection of the icon by the user (e.g., such as detecting the usingtouching the icon) and in response, may start (e.g., which may also bereferred to herein as launching, running, executing, activating and/orinvoking) the control/configuration application 203. Thecontrol/configuration application may be started in other ways,including the network device being configured to automatically start theapplication upon being reset and/or powered on. In response to beingstarted or launched, the control/configuration application (in additionto performing security/authentication procedures, for example) maycommunicate one or more messages to the system controller, for example,to obtain/request/query for various information, such as status/stateand/or configuration information of the load control system, and usethis information to initially generate and display to the user via thedisplay screen of the network device 280 a graphical user interface.Again, at starting, for example, the control/configuration applicationmay also communicate with Wi-Fi enabled devices, for example, thenetwork devices have been configured to communicate with. Thereafter,the control/configuration application may continue to request and/orreceive various information from the system controller at various timesdepending on what information the control/configuration application mayneed to display to the user and/or is being generated by the systemcontroller. Again, the control/configuration application 203 may alsocommunicate with Wi-Fi enabled devices in a similar fashion.

Upon receiving information requests from the control/configurationapplication 203 (such as requests for status and configurationinformation), the system controller may respond by communicating withcontrol devices and/or a database(s), for example, to determine andprovide the requested information and respond to thecontrol/configuration application with one or more response messages. Inaddition to determining status and configuration of the load controlsystem, for example, the control/configuration application 203 may alsoallow a user to communicate messages to the system controller to modify,edit, or change the configuration and/or state of the load controlsystem as further described herein. In addition, the system controllermay also asynchronously provide status and configuration information tothe control/configuration application (e.g., provide an indication ofstatus/state changes of control devices without thecontrol/configuration application querying for such changes). Thecontrol/configuration application may use this information to updatevarious graphical user interfaces displayed to the user via the networkdevice 280. Again, Wi-Fi enabled devices and the control/configurationapplication and/or network device may interact in similar fashions.

Before turning to the various graphical user interfaces thecontrol/configuration application 203 may provide to a user, adescription of example types of information the control/configurationapplication may request/receive and/or configure, for example, togenerate interfaces is discussed. For example, as described herein, thecontrol/configuration application may request/obtain this informationfrom another device (e.g. system controller and/or one more controlsource devices). Also, or alternatively, the information may bemaintained or stored locally (e.g., stored at the memory device(s) 204).In addition to receiving this information, the control/configurationapplication may also alter such information at the system controller, asdescribed herein.

The control/configuration application may request/obtain informationrelated to the configuration and current state/status of a load controlsystem from another device in the load control system, such as thesystem controller and/or one or more control source devices (e.g., theremote-control device 122). Also, or alternatively, the network device280 may itself store or maintain the configuration and currentstate/status information (e.g. or a subset of the configuration andcurrent stat/status information), and the control/configurationapplication 203 may request/obtain this information from the memorydevice(s) 204. Such information may include, for example, the specificcontrol devices that are part of the load control system including anidentifier that indicates the type of the control device The specificcontrol device types may include, for example, one or more lightingcontrol devices (also referred to herein as lighting devices) that eachdirectly controls one or more respective electrical lightingloads/lights, one or more temperature control devices (such as andhereinafter also referred to as a thermostat device(s)) that directlycontrol respective HVAC systems, one or more ceiling fan devices (alsoreferred to herein as fan devices) that each directly controls one ormore respective fans (e.g., on, off, fan speed), one or more audiocontrol devices (e.g., a speaker system), and one or more window shadedevices that each directly controls positions or levels of one or morerespective shades (One will recognize that while shade devices andshades are discussed herein as an example of motorized window treatmentsand window covering, other types of motorized window treatments andwindow coverings are possible such as drapes, curtains, blinds, etc.).

The control devices may include one or more keypads, such aswall-mounted keypads, tabletop keypads, and/or remote-control/handheldkeypads and devices. As an example, a given keypad may include one ormore actuators such as buttons (although other types of actuators arepossible), and may be configured to control one or more controldevices/electrical loads (e.g., lighting control devices/lightingload(s), HVAC system(s), shade(s), fan(s), and/or speaker(s), etc.). Akeypad may include different types of actuators such as on/offactuators, raise lower actuators for lights or shades, fan speedactuators, scene actuators, etc. A scene actuator may set one or morecontrol devices/electrical loads controlled by the keypad to a pre-setconfiguration.

The configuration and current state/status information may also includea location indicator for each control device that may indicate alocation of the device within the user environment and/or the locationof the electrical loads the device controls. This indicator may be inthe form of a location name (e.g., a text string) and/or an indicatorthat may be translated into a location name (e.g., a text string),although other mechanisms may be used. For example, assuming the userenvironment is a home, possible locations may include standard locationslike “kitchen,” “living room,” “family room,” “dining room,” “masterbedroom,” “bedroom,” “master bathroom,” “bathroom,” “basement,” “frontporch,” “office,” “lobby,” “conference room,” etc. Locations may alsoinclude sub-locations in a room like “basement—sitting area,” “basement—game area,” basement—work area,” basement—storage area,” etc. Locationsmay also include user defined/customized locations like: “Mary'sbedroom,” “John's bedroom,” etc. The location of a control device may beprogrammed into the load control system (and stored in database, forexample) by a user when installing the system within the userenvironment. One will recognize these are examples.

For lighting control devices, the configuration and current state/statusinformation may also include a type indicator that may indicate a typeof a lighting load(s) (also referred to herein as a light(s)) controlledby the control device. A type of a lighting load may include, forexample, the function/purpose of the lighting load within its definedlocation and/or indicate/suggest a specific location of the lightingload within its defined location (e.g., ceiling light vs floor lamp). Atype indicator may be in the form of a name/function (e.g., a textstring) and/or an indicator that may be translated into a name/function(e.g., a text string), although other mechanism may be used. As anexample, assuming the user environment is a home, standard types mayinclude ceiling or overhead light, chandelier, pendant(s), tablelamp(s), floor lamp(s), sconce(s), sink light(s) (e.g., for a kitchen orbathroom), island light(s) (e.g., for a kitchen), closet light(s),accent lights, downlights, desk area lights, etc. Types may also includeuser defined/customized types. The type of lighting load may beprogrammed into load control system (and stored in a database, forexample) by a user when installing the system within the userenvironment. One will recognize these are examples. Types may also applyto other control devices such as fans, shades, and keypads. Again, thetype indicator may provide an indication of a specific function and orlocation within the device's defined location. Other example types mayinclude “left shade,” “right shade,” “center shade,” “wall keypad,”“tabletop keypad,” etc.

The control/configuration information may also include an indication ofan icon to be used with applications (such as the control/configurationapplication) to graphically represent the control device on a graphicalinterface. The type of icon to associate with a device may be programmedinto load control system (and stored in a database, for example) by auser or automatically when installing the system within the userenvironment.

The control/configuration information may also include a currentstatus/state and/or configuration of one or more of the control devices.For example, for a lighting control device the status information mayinclude whether the respective lighting load(s) are in an on or offstate, and if in the on state whether it is a dimmed state and possiblyfurther the dimming level, color setting, vibrancy setting, etc. Thecontrol/configuration application may allow the user to modify scenesand/or to create new scenes, for example, via the network device. For anoccupancy sensor, the status information may include, for example,whether the sensor has detected an occupancy event/condition and/or isin an occupancy state, has detected a continued occupancyevent/condition and/or is in a continued occupancy state, and/or hasdetected a vacancy condition and/or is in a vacancy state. Again, theseare examples and other information is possible.

As another example, a device in the load control system, such as thesystem controller and/or one or more control source devices, maymaintain information related to one or more pre-programmed scenes thatmay be actuated by a user from an application, such as thecontrol/configuration application 203 or a control source device, suchas the remote-control device 122 or other type of keypad as describedherein. A scene may include, for example, certain settings for one ormore lights, shades, etc. The device may maintain respective sceneconfiguration information in a database. The control/configurationapplication may request/obtain information related to thesepre-programmed scenes and as further described below, thereafter allowthe user, via the network device, to a select a given scene, resultingin the control/configuration application instructing the another device(e.g., the system controller and/or one more control source devices) toconfigure control devices according to the selected scene (e.g., set onemore light levels, fan speeds, shade levels, etc.). As also describedbelow, the control/configuration application may allow a user to modifythe pre-programmed scenes maintained and to create and store new scenesthat may subsequently be selected by the user. After the scene arecreated and stored, the scenes may be assigned. For example, a scene maybe assigned to one or more zones in the load control system, and enabledby, for example, pressing a certain button at a remote control device orkeypad.

As a still further example, various time clock schedules may bemaintained where a schedule may be, for example, a certain setting forone or more control devices (e.g., lights, shades, etc.) that the systemcontroller or one more control-source devices automatically configurebased on the schedule. For example, the system controller may maintainrespective time clock schedules in a database and the status of theseschedules, such as whether a given schedule is active, inactive, ordisabled. The control/configuration application may obtain controlinformation related to these time clock schedules and as furtherdescribed below, thereafter allow the user via the network device tomodify these schedules and to create new schedules.

According to another example, a lighting control device may control alighting load (e.g., or a plurality of lighting loads), where thelighting load may include a plurality of multi-colored LEDs. In otherwords, the lighting load may include within a single package, forexample, a number of differently colored emission LEDs and may beconfigured such that the chromaticity output of the LEDs is mixed toproduce light having varying chromaticity coordinates (e.g., colorpoints) within a color gamut formed by the various LEDs that make up thelighting load. As one example, a lighting load may include one or morered LEDs, one or more green LEDs, one or more blue LEDs, and one or morewhite, or substantially white LEDs (e.g., such as yellow and/or mintgreen LED(s)), which may be collectively referred to herein as a RGBWlighting load. Although the RGBW lighting load is described herein witha combination of four LEDs of certain colors, other combinations of LEDs(e.g., more or less LEDs and/or different color LEDs) may be used.

The control/configuration application may be used to configure a CRIvalue of one or more lighting loads. A CRI value greater than or equalto a threshold (e.g., a CRI value of 90) may be desirable and may bereferred to herein as “optimal,” “optimized,” or “maximized.” That said,other ranges (e.g., smaller and/or larger ranges) may also be considered“optimal,” “optimized,” or “maximized.” In certain instances (e.g.,depending on distance between the selected color setting and theblack-body curve), the CRI value of a lighting load may be increased toa value greater than or equal to a target CRI value. For example, thetarget CRI value may be 90. One will appreciate, however, that thetarget CRI value may be other values. That is, the target CRI value maybe a value which may be considered a desirable threshold that a systemmay attempt to achieve give the certain characteristics of the loadcontrol system and/or lighting control devices (e.g., quality of theLEDs used in a lighting load).

A load control system may be configured and/or controlled according toone or more defined scenes. Also, or alternatively, the load controlsystem may be further divided into one or more areas or locations (e.g.,depending on the size of the load control system or user environment),and each of the areas or locations within the load control system may beconfigured and/or control according to one or more scenes. The scenesmay be activated, for example, in response to a button press at acontrol source device (e.g., remote control device 122), via a graphicaluser interface on a network device (e.g., the network devices 144, 280),and/or based on a time clock, as described herein. Also, oralternatively, a load control system may be configured and/or controlledaccording to natural show or natural lighting configuration, which asdescribed herein, may be activated in response to a button press at acontrol source device, via a graphical user interface at a networkdevice, and/or based on a time clock etc. As described herein, a naturalshow or natural lighting configuration may be defined separately from ascene, or assigned to a scene (e.g., such that activating a sceneenables a natural show or natural light configuration). Further, acontrol/configuration application (e.g., the control/configurationapplication 203) may display one or more graphical user interface toallow a user to define the scenes and/or configure the natural show ornatural lighting settings.

As described herein, the devices in a load control system may be groupedor organized together based on their respective location within the userenvironment. For example, the devices in a load control system may begrouped and/or organized based on their respective location in the userenvironment (e.g. the devices in a single room may be organized orgrouped together). After the devices are grouped or organized based ontheir location in the user environment, the devices may also be assignedto a certain zone. For example, the lighting devices in a certainlocation of a user environment may be assigned to a zone based on theirrespective function (e.g., the lighting control devices that areintended to emit light a certain surface, such as desk, may be grouped,or organized together in a “Desk Area” zone).

Grouping or organizing the devices in a load control system based ontheir location and then assigning them to a zone (e.g., based on theirfunction) may allow a user to configure or control the devices within aload control system more efficiently. For example, as the number ofdevice in the load control system increases, the settings that may beconfigured by the user may also increase. And without grouping ororganizing the device into a more manageable subset of devices, the usermay fail to accurately and efficiently control the increased number ofdevices in the load control system. Moreover, the capabilities and, as aresult, the configurable settings of each of the devices may differ,further increasing the complexity of configuring or controlling the loadcontrol system. If, however, the devices are grouped by their respectivelocation and then assigned to a zone (e.g., based on their respectivefunction), the user may configure the devices in the load control systemby zone, which may improve the accuracy and efficiency of configuringand controlling the load control system.

After the devices in a load control system are organized and grouped bylocation and subsequently assigned to a zone, a user may collectivelyconfigure or control the devices that are assigned to a given zone.Further, since the devices that are assigned to a given zone based ontheir respective function, the settings for devices in that zone (e.g.,lighting intensity settings and/or color settings) may be configured tobe the same, which may improve the accuracy and efficiency ofconfiguring and controlling the load control system.

FIGS. 3A and 3B are flowcharts that illustrate example procedures forconfiguring or controlling a load control system. Referring first toFIG. 3A, there is shown an example procedure 300 for performing vibrancycontrol in a load control system. The procedure 300, or portionsthereof, may be performed by a control/configuration application, suchas the control/configuration application 203, and may enter at 301. Forexample, the procedure 300 may enter in response to an indication from auser to update or configure the system configuration data (e.g.,control/configuration information and/or current state/statusinformation) for a load control system (e.g., via a network devices,such as the network devices 144, 280). The procedure 300 may beperformed after the devices in a load control system have been groupedor organized by their respective location in a user environment andsubsequently assigned to zones. Also, or alternatively, the procedure300 may be performed prior to the devices in a load control system beinggrouped or organized by their respective location in a user environmentand/or assigned to a zone, which may be stored and/or maintained in thesystem configuration data.

At 302, the control/configuration application may retrieve the systemconfiguration data for a given zone. For example, the systemconfiguration data may indicate the lighting control device(s), which,as described herein may perform control of a corresponding lightingload, that are assigned to the zone. The system configuration data mayindicate or otherwise describe the current state orcontrol/configuration information defined for the lighting controldevice(s) assigned to the zone. For example, the system configurationdata may include control/configuration information comprising lightingcontrol parameters for controlling the corresponding lighting loads ofthe lighting control devices. As described herein, the lighting controlparameters may indicate the lighting intensity settings and/or the colorsettings. The lighting intensity settings may indicate the lightingintensity settings, the color settings, the vibrancy setting, etc. towhich lighting control devices in the zone are to be controlled. Thecolor settings may include a color value (e.g., x-y chromaticity values,CCT value, etc.) to which the lighting load of the lighting controldevices in the zone are to be controlled. The color value may be acoordinate on the color gamut or a color temperature value. The colorvalue may identify a full color value or a CCT value of white light onthe black-body curve. The lighting control parameters may also indicatevibrancy settings (e.g., vibrancy mode and/or vibrancy value) forcontrolling the lighting control devices in the zone. The vibrancysettings may include a selection of the vibrancy mode, such as the autovibrancy mode, or the adjustable vibrancy mode for the lighting controldevices assigned to the zone. The vibrancy settings may also include thevibrancy value for controlling the lighting control devices assigned tothe zone.

As described herein, the system configuration data may be retrieved froma single device (e.g., a system controller, such as the systemcontroller 150, or a network device), or portions of the systemconfiguration data may be retrieved from multiple devices (e.g., asystem controller, network device, one or more control source devices,and/or one or more control target devices). The system configurationdata may also be obtained from devices external to the load controlsystem, such as from cloud based system or other load control systems towhich a given load control system is integrated with. The systemconfiguration data may include predefined control/configurationinformation and/or control/configuration information based on a userselection (e.g., a user may provide a selection, via thecontrol/configuration application 203).

After retrieving the system configuration data, thecontrol/configuration application may display a representation of thesystem configuration data (e.g., or a portion of the systemconfiguration data). For example, the control/configuration applicationmay display a representation of a defined scene for controlling one ormore zones in an area of user environment or load control system via agraphical user interface, as described herein. As described herein, oneor more lighting control devices configured to control a correspondinglighting load may be assigned to each of the one or more zones. Thegraphical user interface may display various controls or controlinterfaces based on the lighting control device/lighting loads assignedto a given zone. For example, the graphical user interface may display alighting intensity (e.g., via lighting intensity bar) for each of thelighting control device(s) assigned to the zone and/or a palette thatidentifies a color setting for controlling each of the one or more zonesin the scene. The palette may be configured to display colors atdifferent color temperatures at which the lighting controldevices/lighting loads are capable of being controlled to, or a fullcolor gamut of colors at which the lighting control devices/lightingload are capable of being controlled to. If, for example, the systemconfiguration data indicates that a respective vibrancy mode is enabled(e.g., auto vibrancy mode and/or adjustable vibrancy mode is enabled),the graphical user interface may display a vibrancy control interfacefor each of the lighting control device(s) assigned to the zone.

Also, or alternatively, the control/configuration application maydisplay a representation of the system configuration data in the form ofa graph. The graph may include one or more axes (e.g., a colortemperature axis that indicates color temperatures, an intensity axisthat indicates lighting intensity values, and/or a time axis thatincludes a period of time at which the lighting intensity and the colortemperatures are controlled), which may indicate changes in lightingcontrol parameters (e.g., lighting intensity settings, color settings,vibrancy setting, etc.) of the lighting control device/lighting loadsassigned to a given zone over time (referred to herein as natural show).If a respective vibrancy mode is enabled (e.g., auto vibrancy mode oradjustable vibrancy mode is enabled), the graphical user interface mayalso display certain vibrancy control interfaces (e.g., a vibrancy bar).

The control/configuration application may also be configured to receiveupdates or changes to the system configuration data, for example, from auser. As described herein, changes to the system configuration data mayinclude changes or updates to the lighting control parameters (e.g.,lighting intensity settings, color settings, vibrancy settings, etc.)for a defined scene; changes or updates to a natural show (e.g., changesor updates to the lighting intensity settings, color settings, vibrancysettings, etc., over time); etc. Accordingly, the control/configurationapplication may receive changes or updates to the system configurationdata via the displayed lighting intensity, palette, and/or vibrancycontrols.

As described herein, a lighting control device may be set to and/orconfigured according to an auto vibrancy mode or an adjustable vibrancymode. Accordingly, the control/configuration application may determinewhether auto vibrancy mode is selected at 304. When auto vibrancy modeis selected, the control/configuration application may automaticallydetermine a vibrancy value at which to control the lighting load to emitlight at a CRI value that is at or above a target CRI value. Forexample, the control/configuration application may automaticallydetermine the vibrancy value based on a distance between the selectedcolor setting and the black-body curve, such that the lighting loademits light toward, at, or above a target CRI value. Thus, at 306, thecontrol/configuration application may determine a distance between theselected color setting for the lighting load (e.g., which may beindicated or otherwise defined by the system configuration data) and theblack-body curve. Although not show in FIG. 3A, thecontrol/configuration application may also, or alternatively, determinea distance between the selected color setting for the lighting load andanother set of predefined color values (e.g., the color output of awhite or substantially white LED) on the color spectrum. At 308, thecontrol/configuration application may automatically determine a vibrancyvalue based on the distance between the selected color setting for thelighting load and the black-body curve (e.g., or another set ofpredefined color values on the color spectrum). The vibrancy valueautomatically determined at 306 may further be and/or alternatively beconfigured to emit light from the corresponding lighting load toward,at, or above a target CRI value. As described herein, when the autovibrancy mode is enabled, a vibrancy value may be automaticallydetermined based on the selected color setting. Further, theautomatically determined vibrancy value may be updated as the selectedcolor setting is updated (e.g., as the user changes or updates theselected color setting). Accordingly, the actions performed at 306 and308 of the procedure 300 may be performed in response to changes in theselected color settings (e.g., the respective distances and vibrancyvalues may be re-determined in response to changes or updates to theselected color settings).

As described herein, the distance between the selected color setting forthe lighting load and the black-body curve may indicate whether theselected color setting has an equivalent CCT value on the black-bodycurve. If, for example, the distance is less than a distance threshold(e.g., indicating that the color setting has an equivalent CCT value),the automatically determined vibrancy value may be the automaticallydetermined vibrancy that results in the emission of light from thelighting load at or above the target CRI value for the equivalent CCTvalue. In addition, when the distance between the selected color settingfor the lighting load and the black-body curve is greater than thedistance threshold, the automatically determined vibrancy value may be apredefined vibrancy value (e.g., 25%).

As described herein (e.g., with respect to FIGS. 1B and 1C), as theselected color setting nears white or near white light (e.g., nears theblack-body curve), the effect that configuring or controlling vibrancyhas on the light emitted by the lighting load (e.g., the CRI value ofthe light emitted by the lighting load) may increase. As a result, ifthe distance between the selected color setting for the lighting loadand the black-body curve is less than the distance threshold, theautomatically determined vibrancy value may increase. Further, as theselected color setting increases along the black-body curve (e.g., asthe CCT value increase and/or as the selected color setting approacheshigher CCT values), the automatically determined vibrancy value mayincrease (e.g., the contribution of the white or substantially white LEDmay decrease).

The control/configuration application may determine whether adjustablevibrancy mode is selected at 310. As described herein, when adjustablevibrancy mode is selected, the control/configuration application may beconfigured to receive an adjustable vibrancy value at which to controlthe corresponding lighting load. If adjustable vibrancy mode is notselected, the procedure 300 may end at 315. If, however, adjustablevibrancy mode is selected at 310, the control/configuration applicationmay receive the adjustable vibrancy value at 312, for example, via thevibrancy control interface displayed by the graphical user interface(e.g., a vibrancy control bar). As the selected vibrancy valueincreases, the contribution of at least one of the plurality of LEDs inthe corresponding lighting load may decrease. For example, as theselected vibrancy value increases, the contribution of the white (e.g.,or substantially white) LED in an RGBW lighting load may decrease toincrease the vibrancy of reflected light from the lighting load.Additionally, or alternatively, as the selected vibrancy valueincreases, the contribution of at least one of the plurality ofnon-white LEDs in the corresponding lighting load may increase toincrease the vibrancy of reflected light from the lighting load.

At 314, the control/configuration application may generate controlinstructions. For example, depending on the selected vibrancy mode, thecontrol/configuration application may generate control instructionsbased on the automatically determined vibrancy value at 306 or thereceived adjustable vibrancy value at 312. The control instructions may,based on the selected lighting intensity settings, color settings,vibrancy settings, etc., include a lighting intensity settings, a colorsetting, and/or a vibrancy value (e.g., the automatically determinedvibrancy value at 306 or the received adjustable vibrancy value at 312).Also, or alternatively, the control instruction may include anindication or a button press. And, as described further herein, alighting control device that receives the generated control instructionsmay perform control of a corresponding load based on the controlinstructions. For example, the lighting control device may control thecorresponding lighting load to emit light at the lighting intensityvalue and color value indicated by the selected lighting intensitysettings, the selected color settings, and/or the selected vibrancysettings. If, for example, the control instructions include anindication of a certain button press, the lighting control device maydetermine the selected lighting intensity settings, the selected colorsettings, and/or the selected vibrancy settings based on the certainbutton that was pressed (e.g., by retrieving these settings from aninternal storage medium), and control the corresponding lighting load toemit light at those selected settings. That is, the correspondinglighting load may set the intensity of each of its respective LEDs tomaintain the selected color setting and lighting intensity setting whilecontrolling to the vibrancy value (e.g., the intensity or contributionsof each of the respective LEDs). And, when the auto vibrancy mode isselected, the lighting load may set the intensity of each of itsrespective LEDs such the lighting load emits light at a CRI value at, orabove the target CRI value.

The procedure 300 may also be performed in a natural show example. Forexample, if the system configuration data indicates that lightingcontrol devices and corresponding lighting loads assigned to a zone areconfigured with natural show with auto vibrancy mode enabled, thecontrol/configuration application may be configured to automaticallydetermine vibrancy values for each of the selected color settings over aperiod of time. That is, the control/configuration application maydetermine a respective distance between each of the selected colorsetting over the period of time and the black-body curve (e.g., oranother predefined range of color values on the color gamut), and thendetermine respective vibrancy values for each of the selected colorsettings over the period of time to emit light at a CRI value thatachieves the target CRI based on the respective color setting selectedat that time.

Similarly, when the system configuration data indicates that lightingcontrol devices and corresponding lighting loads assigned to a zone areconfigured with natural show and adjustable vibrancy mode enabled, thecontrol/configuration application may receive a selection of theadjustable vibrancy value, and the selection of the adjustable vibrancyvalue may apply to the selected color setting over the period of time.One will appreciate, however, that although the selection of theadjustable vibrancy value may remain the same over the period of time,the intensity or contribution of the white LED in the lighting maydiffer based on the selected color setting. For example, although theselection of the adjustable vibrancy value may remain the same over theperiod of time, the intensity or contribution of the white LED maydecrease as the selected color setting (e.g., CCT value) increase overthe period of time.

Although not shown in FIG. 3A, the control/configuration application mayupdate the system configuration data to reflect the control instructionsgenerated at 314 before exiting the procedure 300 at 315. For example,the control/configuration application may update the systemconfiguration data in response to determining that there are noadditional updates to be made to the system configuration data (e.g.,when the control/configuration application receives an indication from auser that there are not additional updates to the system configurationdata, for example, by selecting a “Save” or “Finished” button, such asthe “Save to Scene” button 438 described herein with respect to FIG.4B).

Referring now to FIG. 3B, there is shown an example procedure 350 forcontrolling a load control system based on a system configuration data,which, as described herein, may be defined or updated using theprocedure 300. The procedure 350 may be performed by a single device.For example, the procedure 350 may be performed by a system controller,a lighting control device, a network device, or another control deviceto perform control using the system configuration data stored thereon.Also, or alternatively, the procedure 350 may be performed by multipledevices (e.g., a portion of the procedure 350 may be performed by afirst load control device and another portion of the procedure 350 maybe performed by a second load control device). For example, the systemcontroller may retrieve the system configuration data (e.g., eitherlocally or from another device) and perform control based on the systemconfiguration data (e.g., by transmitting one or more message thatinclude control instructions to perform control based to one or morelighting control devices based on the system configuration data).

As illustrated in FIG. 3B, the procedure 350 may be performed inresponse to the detection of a triggering event at 351. A triggeringevent may be an event that causes the devices in a load control systemto be controlled according to the system configuration data. Forexample, as described herein, a triggering event may be caused by a useractuation for activating a scene (e.g. by pressing a button thatcorresponds to a scene at a remote control device or keypad); ascheduled event (e.g., based on a time clock); and/or a sensor event(e.g., an occupancy sensor detecting occupancy). Accordingly, the systemconfiguration data may be retrieved at 352. As described herein, thesystem configuration data may be stored at a system controller and/oracross one or more other devices (e.g., remote-devices, network devices,lighting control devices, other control devices, etc.). Therefore, thesystem configuration data may be retrieved from a system controllerand/or from one or other devices in the load control system.

After retrieving the system configuration data, control may be performedbased on the system configuration data at 354. For example, control maybe performed by transmitting one or more messages that include controlinstructions (e.g., the control instructions generated at 314 of theprocedure 300) to the load control device and/or a correspondinglighting load based on the system configuration data (e.g., the lightingcontrol parameters indicated in the system configuration data).Referring now to a lighting control device and corresponding lightingload configured in an auto vibrancy mode or an adjustable vibrancy mode,the control instructions may include the selected lighting intensitysettings (e.g., lighting intensity value), the selected color settings(e.g., x-y chromaticity values or CCT values), and a vibrancy value. Asdescribe herein, the vibrancy value may be an automatically determinedvibrancy value (e.g., when the auto vibrancy mode is enabled), or anadjustable vibrancy value selected by a user (e.g., when the adjustablevibrancy mode is enabled). These control instructions may be transmittedto the lighting control device and/or the corresponding lighting load.In response to receiving these control instructions, the lightingcontrol device and/or corresponding lighting load may, based on thevibrancy value indicated by the control instructions, determinecontribution/intensity of the separately colored LEDs to emit light atthe selected lighting intensity settings and the selected colorsettings. The lighting control device may output the same total colorand/or intensity, while varying the individual contribution/intensity ofthe separately colored LEDs in response to the vibrancy value. As thevibrancy value increases, the contribution/intensity of the non-whiteLEDs may increase and/or the contribution/intensity of the white LED(s)may decrease. As the vibrancy value decreases, thecontribution/intensity of the non-white LEDs may decrease and/or thecontribution/intensity of the white LED(s) may increase. It will beunderstood that the vibrancy value may be a relative value (e.g.,between 0 and 100) that is different for different lighting loads havingdifferent combinations of colored LEDs. The procedure 350 may exit at355.

With reference now to FIGS. 4A to 4D, FIGS. 5A to 5B, and FIGS. 6A to 6Ian example control/configuration application 203, e.g., as illustratedin FIG. 2 , is now described that may execute at least in part on anetwork device 380. Network device 380 may be similar to any of networkdevices 144, as described herein and may be a personal computer (PC), alaptop, a tablet, a smart phone, or equivalent device, for example,although it may also be another type of computing device. Thecontrol/configuration application may be a graphical user interface(GUI) based application that may provide a GUI based interface/GUI based“window(s)” to a user via the network device 380 and that may allow auser of the network device to interact with, control, and/or configurecontrol devices within a user environment (such as control devices of auser environment). Nonetheless, the features and functions of thecontrol/configuration application 203 (shown in FIG. 2 ) describedherein are applicable to other types of control devices, load controlsystems, and communication systems. As an example, the user environmentmay be a residence, home, commercial building, and/or office, and theuser of the network device 280 may be a resident or tenant of the home,commercial building, or office. The control/configuration applicationdescribed herein may be also applicable to other types of userenvironments such as a buildings, hotel, etc. Similarly the user of thenetwork.

Turning now to FIGS. 4A to 4D, FIGS. 5A to 5B, and FIGS. 6A to 6I, theyillustrate example control/configuration applications that may beexecuted at least in part on a network device, such as thecontrol/configuration application 203 of the network device 280, forconfiguring or controlling a load control system. For example, FIGS. 4Ato 4D, FIGS. 5A to 5B, and FIGS. 6A to 6I may illustrate graphical userinterfaces that may be displayed by the control/configurationapplication to display and/or update the system configuration data for aload control system. Again, the network device may be similar to thenetwork devices 144, 280 as described herein and may be a personalcomputer (PC), a laptop, a tablet, a smart phone, or equivalent device,for example, although it may also be another type of computing device.The control/configuration application may be a graphical user interface(GUI) based application that may provide a GUI based interface/GUI based“window(s)” to a user via the network device and may allow a user of thenetwork device to interact with, control, and/or configure controldevices within a user environment (e.g., user environment 102) or loadcontrol system (e.g. the load control system 100). For descriptionpurposes only, the load control system 100 of user environment 102 andthe communication systems described with respect to FIG. 1A will be usedherein as an example load control system and communication system todescribe the control/configuration application. Nonetheless, thefeatures and functions of the control/configuration applicationdescribed herein are applicable to other types of control devices, loadcontrol systems, and communication systems. As an example, the userenvironment 102 may be a residence or home and the user of the networkdevice may be a resident of the home. Nonetheless, the examplecontrol/configuration application may also be applicable to other typesof user environments, such as a building, hotel, etc. and the user ofthe network device may be a system administrator.

Referring now to FIGS. 4A to 4D, there is shown example graphical userinterfaces that may be displayed by the control/configurationapplication. As described herein, a user may interact with the graphicaluser interfaces to configure or control a load control system. Forexample, the graphical user interfaces may provide for the configurationor control of one or more lighting control devices in the load controlsystem, for example, by defining one or more scenes. As describedherein, a scene may include certain settings for one or more lights,shades, etc. And when a scene is activated (e.g., via button press of aremote-control device or keypad) one or more messages that includecontrol instructions may be transmitted to control the respectivedevices in the load control system in accordance with the scene. Also,or alternatively, the graphical user interfaces may provide for theconfiguration or control of one or more lighting control devices in theload control system by defining a natural show or natural lightingconfiguration. As further described herein, a natural show or naturallighting configuration may allow a user to configure or control the oneor more lighting control devices over time.

Referring now to FIG. 4A, there is shown a graphical user interface 410that may be displayed by the control/configuration application. Thegraphical user interface 410 may be displayed to a user via the networkdevice 280, for example. The graphical user interface 410 may bedisplayed by the control/configuration application after the devices ina load control system have been grouped or organized by their respectivelocation in the user environment and subsequently assigned to a zone(e.g., based on their function). For example, the system configurationdata may be generated and stored during a commissioning procedure suchthat control devices may be associated with one another and/or one ormore zones. Scenes may be defined and/or predefined during thecommissioning procedure and stored in the system configuration data,such that the control devices and/or settings for the scenes may bedisplayed on the graphical user interface 410 using thecontrol/configuration application. Also, or alternatively, the graphicaluser interface 410 (e.g., or a similar graphical user interface) may bedisplayed by the control/configuration application before the devices ina load control system have been grouped or organized by their respectivelocation and/or assigned to a zone. For example, the graphical userinterface 410 may be displayed during a design process when the loadcontrol system is being designed. Accordingly, although FIG. 4Aillustrates one type of example graphical user interface that may bedisplayed by the control/configuration application, other types ofgraphical user interfaces may also, or alternatively, be displayed.

The graphical user interface 410 may include a number of tiles 411, 413,415, 417, 419, 421, 423. Each of tiles 411, 413, 415, 417, 419, 421, 423may convey information to the user and/or allow for user-selection forproviding additional information and/or configuration. Each of the tiles411, 413, 415, 417, 419, 421, 423 may provide information about devicesin a preselected area or room, for example, within a floor of abuilding. An energy tile 411 may indicate an amount of energy usageand/or savings. An alerts tile 413 may provide alerts about devices inthe system. A schedules tile 415 may provide information about scheduledevents to the user and/or allow a user to schedule events in the system.For example, after selection of the schedules tile 415, the user mayconfigure lighting schedules for controlling lighting control devices inthe system. A lights tile 417 may provide information about currentlighting configurations in the system and/or allow a user to configurecontrol of lighting control devices and/or lighting loads within thesystem. A shades tile 419 may provide information about current shadeconfigurations in the system and/or allow a user to configure control ofshades within the system. An occupancy tile 421 may provide informationabout current occupancy conditions in the system and/or allow a user toconfigure control of devices within the system in response to occupancyand/or vacancy events/conditions. A devices tile 423 may allow a user tomanage and perform maintenance of devices.

A scene indicator 412 may be displayed in the lights tile 417. The sceneindicator 412 may be an indication of the current scene set for one ormore lighting control devices of the preselected area (e.g., the“Bright” scene as shown in FIG. 4A). The scene indicator 412 may beselectable or configurable, and/or may allow the user to select ordefine the scene(s) for one or more lighting control devices (e.g., theone or more lighting control devices in the preselected area). Afterselecting the scene indictor 412, the control/configuration applicationmay display a graphical user interface that provides a user with theability to configure the settings (e.g., static settings) for one ormore scenes. As an example, after selecting the scene indicator 412, thecontrol/configuration application may display the graphical userinterface 410 a to configure the static settings for one or more scenes,as described herein with respect to FIGS. 4B to 4D.

A natural show indicator 425 may be displayed in the lights tile 417.The natural show indicator 425 may provide an indication that a naturalshow setting has been enabled or disabled for one or more lightingcontrol devices in the preselected area. As described herein, a naturalshow (or natural lighting) feature may allow a user to configure orcontrol the one or more lighting control devices over time (e.g., ascompared to the static configurations that may be configured describedherein, with respect to FIGS. 4A to 4D). For example, a natural show maybe assigned to a scene and/or enabled when the scene is activated (e.g.,via a button press at a remote control device or keypad, via a timeclock schedule etc.). The natural show indicator 425 may be selectableor configurable, and/or may allow the user to select or define thenatural show settings for one or more lighting control devices (e.g.,the one or more lighting control devices in the preselected area orzone). A natural show setting may include a time clock basedconfiguration of one or more lighting control devices where the controldevices may be automatically controlled to change their lightingintensity values/brightness and/or color output over a defined period oftime. After selecting the natural show indictor 425, thecontrol/configuration application may display a graphical user interfacethat provides a user with the ability to configure the natural showsettings. As an example, after selecting the natural show indictor 425the control/configuration application may display the graphical userinterface 510 a to configure the natural show settings, as describedherein with respect to FIGS. 5A to 5B. As another example, afterselecting the natural show indictor 425 the control/configurationapplication may display the graphical user interface 510 a to configurethe natural show settings, as described herein with respect to 5A to 5B.Further, although the natural show indicator 425 is provided on thegraphical user interface 410 for configuring and/or controlling thenatural show, other graphical user interfaces may also be provided forconfiguring and/or controlling the natural show.

As described herein, the devices in a load control system may be groupedor organized by their respective location in a user environment andsubsequently assigned to a zone (e.g., based on their function). Turningnow for FIG. 4B, there is shown an example of the graphical userinterface 410 a that may be displayed by the control/configurationapplication to control the lighting intensity settings, color settings,and/or vibrancy settings defined for scenes (e.g., after selection ofthe scene indicator 412). The graphical user interface 410 a may beprovided for configuring scenes in response to the scene indicator 412(shown in FIG. 4A), for example. As described herein, a scene maycontrol one or more zones in a given location or area of a userenvironment. Thus, the control/configuration application may beconfigured to display the graphical user interface 410 a (e.g., oranother similar graphical user interface) such that a user is providedwith the ability to configure or control devices assigned to each zonebased on their respective functionality and/or capabilities. Forexample, as illustrated in FIG. 4B and as further described herein, thegraphical user interface 410 a may display different types of controlsbased on the functionality and/or capabilities of the devices assignedto each of the zones (e.g., the devices in the “Desk Area 1” zone arecapable of adjusting their lighting intensity and thus control interface418 is display, whereas the devices in the “Hallway zone” are capable oftoggling between an on and off and thus the control interface 430 isdisplayed). The graphical user interface 410 a may include scene icons414. The scene icons 414 may indicate the scenes that are defined, e.g.,for a particular area of the load control system. For example, referringto FIG. 4B, the defined scenes may include: “Bright,” “Cleaning,”“Event,” “Relax,” and “Off” Further, as described herein, each of thesescenes may correspond to a respective button, for example, of a keypadthat is located in given location or area of a user environment.

As described herein, the scenes defined for the load control system(e.g., or a certain area in the load control system) may be storedand/or maintained at a single device (e.g., a system controller) oracross multiple devices (e.g., the system controller, and/or, thenetwork device, one or more control source devices, and/or one or morecontrol target devices). When a scene is selected, one or more messagesthat include control instructions to control the loads as defined by thescene may be transmitted. In addition, the scenes defined for the areaof the load control system may be selected via the graphical userinterface 410 a. The scenes (e.g., and their respective configurations)may be communicated to a system controller. Each of the scenes may beseparately configurable and/or programmable via the graphical userinterface 410 a. Further, the graphical user interface may indicate thescene that is presently being configured/programmed and/or is currentlyactive may be indicated. For example, referring to FIG. 4B, the “Bright”scene may be the scene that is presently being configured/activated(e.g. as indicated by the “Bright” scene icon being highlighted).

After configuration, a scene may be activated via a graphical userinterface, such as the graphical user interface 410 a (e.g., or adifferent graphical user interface), or a control device, such as theremote-control device 122 and/or keypad. For example, as describedherein, the control device may include one or more buttons, each ofwhich may correspond to a configured scene. The scene may then beactivated by actuating (e.g., pressing) the button that corresponds tothat scene. Upon activation, the configurations defined for the scenemay be retrieved. For example, the configurations may be stored andretrieved from the control device, and/or a system controller, such asthe system controller 150, or the load control device(s)/lightingcontrol device(s) themselves. Also, or alternatively, the configurationsfor the scene, or portions thereof, may be stored and retrieved frommultiple devices. For example, part of the configuration for a scene maybe stored and retrieved from the system controller, and another part ofthe configuration for the scene may be stored and retrieved from thecontrol device and/or the load control device(s)/lighting controldevice(s) themselves. After the configuration for the scene has beenretrieved, one or more messages including control instructions may betransmitted to control one or more load control devices based on theconfiguration of the scene.

The load control devices configured for being controlled in a givenscene may be organized or grouped into one or more zones. For example,the load control devices may be organized or grouped into a given zonebased on their location, function, etc. Referring to FIG. 4B, forexample, the “Bright” scene may include lighting control devices thatare organized or grouped in a “Front Downlights” zone, a “Desk Area”zone, and an “Accent Lights” zone. Each of the zones may be separatelycontrollable via a respective control interface. For example, the “DeskArea” zone may be controlled by the control interface 440 and the “FrontDownlights” zone may be controlled by control interface 452.

The control interface of a respective zone may vary based on the loadcontrol device and/or lighting loads associated with the zone. Forexample, referring to FIG. 4B, the load control device(s) associatedwith the “Desk Area” zone may be a dimmer. Accordingly, controlinterface 440 may be configured to include one or more controlinterfaces to enable the user to control the dimmer. For example, asillustrated in FIG. 4B, the control interface may include an indicator432, control line 436, and/or actuators 422, 420 a, 420 b. The indicator432 may indicate the configured lighting intensity for the “Desk Area”zone (e.g., 50% as shown in FIG. 4B). As described herein, the actuator422 may be actuated along the control line 436 to control the lightingintensity of the “Desk Area” zone. Similarly, actuator 420 a may beactuated to decrease the lighting intensity of the “Desk Area” zone andactuator 420 b may be actuated to increase the lighting intensity of“Desk Area” zone. Each of actuators 420 a and 420 b may be configured toincrease/decrease the intensity by a set amount, such as 1%.

The control/configuration application may be configured to allow theuser to rename a scene and/or the corresponding zones. For example, asillustrated in FIG. 4B, the graphical user interface 410 a may include arename light and scenes button 426. The rename light and scenes button426 may be actuated to adjust the name of the zones and/or scenesdefined for the area of the load control system. The graphical userinterface 410 a may include a save scene button 438, which, whenactuated, may save the configuration of and/or changes to a respectivescene.

The control/configuration application may be configured to provide theuser real-time feedback of the settings being configured. For example,the graphical user interface 410 a displayed by thecontrol/configuration application may include a “Live Changes Enabled”actuator 428. When the Live Changes Enabled actuator 428 is enabled(e.g., as show in FIG. 4B), the lighting controls that are defined bythe user via the graphical user interface 410 a may be present at therespective lighting control devices in the load control system. Forexample, control instructions that indicate the defined lightingintensities may be transmitted to the respecting lighting controldevices, and the lighting control devices may transition to indicate thelighting intensities. In response, the user may be provided with liveand real-time feedback of the defined lighting intensities. When the“Live Changes Enabled” actuator 428 is disabled, the lighting controlsmay be defined by the user via the graphical user interface 410 a andmay be saved for being implemented in the defined zones in the area whenthe defined scene is triggered (e.g., via occupancy event/condition,actuation of a button, a scheduling event, etc.).

A scene may define the lighting intensity settings, color settings(e.g., x-y chromaticity values or CCT values), and/or vibrancy settings(e.g., vibrancy mode and/or vibrancy value) of a respective zone, andthe control/configuration application may provide the user with theability to configure the lighting intensity settings, color settings(e.g., x-y chromaticity values or CCT values), and/or vibrancy settings(e.g., vibrancy mode and/or vibrancy value) defined by the scene (e.g.,to a user selected color point along the black-body curve).

The graphical user interface 410 a may include a control interface 440to control the lighting intensity and color temperature defined for azone (e.g., the “Desk Area” zone as shown in FIG. 4B), for example, upondetecting that the user has selected the warm/cool actuator 446. Thecontrol interface 440 may include an indicator 442, a palette 448, anactuator 444, and/or a control line 450. The palette 448 may show arange of colors ranging from cool colors 443 a at the top of the palette448 to warm colors 443 b at the bottom of the palette 448. As describedherein, these colors may correspond to colors that lie along theblack-body curve. For example, the palette 448 may show colors along arange of correlated color temperatures (CCTs) ranging from “warm white”(e.g., roughly 2600 K-3000 K) at 443 b, to “neutral white” (e.g., 3000K-5000 K) to “cool white” (e.g., 5000 K-8300 K) at 443 a. As oneexample, the range CCTs may be from 1400K to 7000K, although otherexamples are possible.

Superimposed over the palette 448 may be an actuator 444. The actuator444 may be movable/slide-able (e.g., here vertically movable) along thecontrol line 450 to select different CCTs along the black-body curve.Accordingly, actuator 444 may allow a user to configure the lightingcontrol device(s) such that the lighting load(s) produces colored lightat a color point along the black-body curve. Assuming the lightingload(s) is producing light at a color point along the black-body curveat a time prior to actuator 444 being selected by the user, thecontrol/configuration application may display actuator 444 at a relativepoint along control line 450/palette 448 as shown in FIG. 4B to indicatethe color being produced by the lighting load(s). Similarly, indicator442 may also display the corresponding color. Alternatively, if thelighting load(s) is not configured to produce light at a color pointalong the black-body curve (or is out of range of palette 448) at a timeprior to actuator 444 being selected by a user, thecontrol/configuration application may not display actuator 444. Theactuator 444 may only appear once the user interacts with palette 448.And, as described herein, if the “Live Changes Enabled” actuator isenabled, the lighting loads may adjust their respective color in realtime as the actuator 444 is moved across the control line 450.

The control interface 440 may include similar indicators and/or controlsfor controlling the intensity of the lighting control devices asillustrated in the control interface 418 shown in FIG. 4B. For example,the control interface 440 may include an indicator 432, control line436, and/or actuators 422, 420 a, 420 b. The control interface 440 mayallow the user to control the intensity and color temperature oflighting control devices in the defined zone.

A scene may provide for full color control of a respective zone, and thecontrol/configuration application may provide the user with the abilityto configure the full color settings defined by the scene. Accordingly,the graphical user interface 410 a may be displayed by thecontrol/configuration application to control the full color defined by azone for the respective scene. The graphical user interface 410 a mayinclude a control interface 452 to control the lighting intensity andfull color for a zone (e.g., the Front Downlights zone as shown in FIG.4B). The control interface 452 may include control line 436 andactuators 422, 420 a, 420 b to control the lighting intensity of the“Front Downlight” zone. The control interface 452 may include a palette454 showing a plurality of colors that lie within the color gamut formedby the various RGBW LEDs, for example, that make up the one or morelighting loads in the defined zone.

The one or more lighting loads in the defined zone may be controlled toprovide full color and/or the warm/cool colors on the black-body curve.The control interface 452 may include a warm/cool color tab 421 a andfull color tab 421 a. Selection of the warm/cool color tab 421 a maydisplay a palette in the control interface 452 that is similar to thepalette 448 shown in the control interface 440 for the “Desk Area” zoneto allow the user to define warm/cool color temperatures for thelighting control devices in the “Front Downlights” zone. Selection ofthe full color tab 421 b, however, may display the palette 454 thatprovides colors available for full color control.

Similar to selecting a certain CCT, a user may select a location withinthe color palette 454 to define a color for the corresponding zone. Asillustrated in FIG. 4B, the color palette 454 may include a plurality ofcolors that lie within the color gamut formed by the various RGBW LEDs,for example, that make up the lighting load(s) such that different colorbands are displayed from top to bottom (e.g., red, yellow, green, teal,blue, purple, etc.). The color palette 454 may be displayed such that auser may select the x-y chromaticity coordinates corresponding to agiven color. The color palette 454 may include white colors on thefar-right side of the color palette 454, though the white colors may belocated in other areas of the color palette 454.

As illustrated in FIG. 4B, the control interface may identify a userselection on the color palette 454. Superimposed over the palette 454may be an actuator 458 that identifies a user selection within the colorpalette 454. The actuator 458 may be movable/slide-able (e.g., up, down,left, right, etc.) by the user to any of a plurality of locations/colorswithin palette 454. The graphical user interface 410 a may displaytogether with actuator 458 two perpendicular control lines thatintersect at the center of the actuator 458. These control lines and theintersection point may move with the actuator 458 as it is moved by auser within palette 454, or as the user selects another location withinthe palette 454 independently. These control lines may assist the use inmoving actuator 458 either horizontally or vertically or diagonally,etc. Accordingly, actuator 458 may allow a user to configure the zonesuch that the zone produces colored light at a color point that lieswithin the color gamut formed by the various RGBW LEDs, e.g., that makeup the one or more lighting loads of the defined zone.

The color gamut formed by the various RGBW LEDs that make up thelighting load may be referenced using an x-y chromaticity coordinatesystem. Accordingly, the control interface 452 may include a coordinateindicator 456. The coordinate indicator 456 may illustrate the x-ychromaticity coordinates of the selected color. For example, referringto FIG. 4B, the color selected for the Front Downlights zone may beindicated by the x-y chromaticity coordinates [0.123, 0.455].

Upon the full color tab 421 b being actuated by a user from controlinterface 452, or prior to the color being defined for the zone, thecontrol/configuration application may initially display controlinterface 452 without actuator 458 and without the control lines, asshown in FIG. 4B. Upon the user performing a selection within thepalette 454, the graphical user interface 410 a may display actuator 458and the control lines at a relative point within palette 454 to indicatethe color being defined and/or produced by the one or more lightingloads within the zone.

The control/configuration application may provide a user with theability to configure advanced options for a scene (e.g., timing options,such as fade and/or delay times, and vibrancy). Accordingly, graphicaluser interface 410 a displayed by the control/configuration applicationmay receive an indication from the user to allow for the configurationof advanced options. For example, as illustrated in FIG. 4B, thegraphical user interface 410 a may include an icon such as a “ShowAdvanced Options” button 460, which, when actuated by the user may causethe graphical user interface 410 a to display advanced options forcontrol of a scene.

FIG. 4C shows an example of the graphical user interface 410 adisplaying advanced options for control of a scene. As described herein,control/configuration application may display the graphical userinterface 410 a in response to receiving a user indication to configureadvanced options (e.g., actuating or selecting the “Show AdvancedOptions” button 460). Further, as shown in FIG. 4C, the graphical userinterface 410 a may include one or more interfaces to configure theadvances options, such as: an Include box 462, Fade time box 464, Delaytime box 466, and/or Vibrancy selector 468 for each of the respectivezones in the area. When the Include box 462 is selected (e.g., as shownin FIG. 4C), the respective zone may be included in the scene. Forexample, referring to FIG. 4C, the Front Downlight and Desk Area zonemay be included in the Bright scene, and when the Bright scene isactivated the lighting control device(s) and/or lighting load(s)assigned to the Front Downlight and Desk Area zones may be controlled tothe settings defined in the Bright scene. When the zone is included inthe scene and the user selects the “Save to Scene” button 438, thelighting intensity and/or color temperature settings that are defined inthe graphical user interface 410 a may be generated and stored forcontrolling the zone in response to the scene being triggered. If,however, a zone is not included in a scene (e.g., because an indicator,such as the Include box 462, is not selected), the lighting controldevice(s) and/or lighting load(s) assigned to the zone may remain attheir current settings. For example, the graphical user interface 410 amay also include an indicator for each of the individual settings (e.g.,lighting intensity, color) defined for a given zone. When an indicatorfor a respective setting is “included,” the lighting control device(s)and/or lighting load(s) assigned to the zone may be controlled todefined value of that setting. Similarly, when an indicator for arespective setting is not “included,” the lighting control device(s)and/or lighting load(s) assigned to the zone may remain unchanged whenthe scene is activated.

The control/configuration application may further provide the user withthe ability configure the vibrancy settings (e.g., vibrancy value)defined by a scene for a respective zone. For example, thecontrol/configuration application may display a graphical user interface410 a that includes a “Vibrancy” selector 468, which may be used by theuser to select and/or configure the vibrancy for a particular zonewithin a scene. As indicated above, the vibrancy may not change (orsubstantially change) the color point/chromaticity coordinates of thecolor being produced by the lighting load. The vibrancy may, however,alter the contribution of each of the RGBW LEDs, for example, ingenerating the colored light, which may include reducing theintensity/contribution of the white LED(s) for example, thereby makingcertain objects in a space appear more vibrant.

The vibrancy may adjust the wavelength of the light emitted by the zone,which may affect the color of the light (e.g., the reflected light) onobjects within the zone. Increases and/or decreases in vibrancy mayincrease/decrease saturation of the color of objects in the area withoutchanging the color of the light when the user looks at the light (e.g.,the color of the emitted light). The Vibrancy selector 468 may allow theuser to select a relative level of vibrancy (e.g., between zero andone-hundred percent) for increasing/decreasing the vibrancy of the oneor more lighting loads for a defined zone. Changing the relative levelof vibrancy may include decreasing or increasing the intensity of one ormore white LEDs that make up the one or more lighting loads for adefined zone, thereby increasing or decreasing vibrancy, respectively.Changing vibrancy in this manner may also include changing theintensities of other LEDs (e.g., red, green, and/or blue LEDs) of theloads in the zone to maintain the same color output of the lightingloads (e.g., to maintain the same (or approximately the same)chromaticity coordinates of the mixed color output of the lighting loadsin the zone). As described herein, the effect that configuring orcontrolling vibrancy (e.g., or the degree to which it can be controlled)has on the light emitted by the lighting load (e.g., the CRI value ofthe light emitted by the lighting load) may be based on the distancebetween the selected color setting and the black-body curve (e.g., oranother predefined range of values, such as the color output of a whiteor substantially white LED within a respective lighting load). Vibrancyselector 468 may be referred to as an adjustable vibrancy mode.

The control/configuration application may provide the user withinformation about how vibrancy may affect objects within the loadcontrol system. For example, the control/configuration application maybe configured to display an information button 469, which may beselected by a user. In response to selecting the information button 469,the control/configuration application may display information about theeffects of vibrancy and how the vibrancy may be selected for a zone bythe user. For example, FIG. 4D illustrates an example display 474 thatmay be shown if the user selects the information button 469.

The vibrancy may be changed for each of the zones that are configuredfor control along the black-body curve. The vibrancy may be enabled forzones that are defined for control using the warm/cool color temperaturepalette. The vibrancy may be controlled for lighting control devices ina zone that are being controlled along the black-body curve, as thelighting control devices may be using a number of colored LEDs togenerate the color temperatures that are generated along the black-bodycurve, while also allowing variation in the use of different LEDs toincrease the color being reflected to saturate the colors in the area(e.g., by reducing the intensities of the white LEDs). For zones thatare being controlled using full color, the vibrancy control may belimited to colors that are within a predefined range of the colors. Forexample, referring to the color palette 454 shown in FIG. 4B, thevibrancy control may be limited to a predefined set of colors on theright side of the palette 454 indicated in FIG. 4B (e.g., based on arespective color's distance from the black-body curve, as describedherein). The predefined colors may be the 10% or 20% of colors on theright side of the palette. Vibrancy control may be disabled or set to adefault value when the user selects colors in the palette that areoutside of this predefined set of colors, as it may not be possible torender these colors in multiple ways using, for example, differentintensities of RGB and white LEDs. One will recognize that the abilityto control or not control vibrancy for colors on the right of thepalette may be based on the number of different color LEDs that comprisea lighting load(s).

Referring again to FIG. 4C, the graphical user interface 410 a maycontrol the lighting intensity of different zones of lighting controldevices separately, while controlling the color temperature of thedifferent zones in uniform. For example, the graphical user interface410 a may include control interfaces 470 a, 470 b to control thelighting intensities of two or more zones (e.g., Desk Area 1 and DeskArea 2) separately and control interface 472 to control the colortemperature of the two or more zones in uniform. The control interfaces470 a, 470 b may each include an indicator 432, a control line 436, andactuators 422, 420 a, 420 b to separately control the lighting intensityof their respective zones or lighting control devices. Similarly, thecontrol interface 472 may include an indicator 442, a palette 448, anactuator 444, and/or a control line 450 to uniformly control the colortemperature of the zones. Though control interface 472 includes awarm/cool color palette 448 for setting a color temperature along theblack-body curve, full color control may similarly be implemented.

As described herein, the control/configuration application may provide auser with the ability to configure or control the lighting controldevices in a zone over time. For example, the control/configurationapplication may display one or more graphical user interfaces thatenable the user to change the color and/or lighting intensities of thelighting control devices. Further, when the lighting devices areconfigured to change in color and/or lighting intensity over time, thelighting devices may simulate a natural lighting functionality, whichmay be referred to herein as natural light and/or natural show. Asdescribed herein, natural lighting functionality may include controllingone or more lighting control devices/lighting loads to emulate a sunriseand a sunset, and may further include emulating natural light/sunlightbetween sunrise and sunset. As described herein, natural lighting ornatural show may be enabled or disabled based on: a schedule (e.g., atime clock); an event (e.g., by an occupancy event triggered by anoccupancy sensor); and/or by assigning and enabling natural show to ascene (e.g., assigning natural show to a scene that is enabled inresponse to pressing a button at a remote control device). FIGS. 5A to5B illustrate example graphical user interfaces that may be displayed bythe control/configuration application to configure or control naturalshow.

Referring now to FIG. 5A, there is shown another example graphical userinterface 510 a that may be displayed by the control/configurationapplication to a user via a network device. For example, the user mayuse the graphical user interface 510 a to enable and/or control naturallighting functionality (also referred to herein as a natural show) forone or more lighting control devices (e.g., after selection of thenatural show indicator 425 on the lights tile 417 shown in FIG. 4A oranother graphical user interface). The natural lighting functionalitymay change the color temperature and/or lighting intensity of one ormore lighting control devices in a preselected area to simulate a changein color temperature/lighting intensity of natural lighting over thecourse of a period of time (e.g., a day, a portion of a day, etc.). Thenetwork device may communicate with the lighting control devices, forexample, via a system controller as described herein. For example, thenatural lighting functionality may be defined at the network device andstored at the system controller and/or a control device and/or thelighting control devices for being implemented in the lighting controldevices in a given location or area in the user environment and assignedto a certain zone(s). Further, the natural lighting functionality may beassigned to a scene and/or may be activated, for example, by pressing abutton on a control device or the network device. Natural lightingfunctionality may include emulating sunrise, sunset, and naturallight/sunlight there between. Upon displaying interface 510 a, thecontrol/configuration application may display a defaultconfiguration/previously defined configuration (either defined by theload control system or previously defined by a user, for example), andmay further allow the user to modify the configuration.

As shown in FIG. 5A, graphical user interface 510 may display a graph504. The graph 504 may include one or more x axes and/or y axes. Forexample, the graph 504 may include a color temperature axis 506, anintensity axis 510, and/or a time axis 508.

The color temperature axis 506 may represent a color temperature (CCT)to which one or more lighting control devices (e.g., one or more LEDlights) within a zone (e.g., a room within a building) may beconfigured/controller. The color temperature axis 506 may be range ofnumbers of color temperatures along the black-body curve. For example,the color temperature axis 506 may range from 2000K to 7000K, or anotherrange. Cooler color temperatures may be indicated with a cooler color(e.g., shades of blue to indicate cooler color temperatures). Warmercolor temperatures may be indicated with a warmer color (e.g., yellow,orange, or red to indicate warmer color temperatures). The colortemperature axis 506 may be located as a y-axis on the left-hand side ofthe graph, though the color temperature axis 506 may be located on otherportions of the graph (e.g., the right-hand side of the graph).

The intensity axis 510 may represent a lighting intensity to which oneor more lighting control devices within the zone may beconfigured/controlled. The intensity axis 510 may range from, forexample, 0% to 100%. The intensity axis 510 may be located as a y-axison the right-hand side of the graph, though the intensity axis 510 maybe located on other portions of the graph (e.g., the left-hand side ofthe graph).

The time axis 508 may display a time of day in a number of predefined oruser-defined increments. The length of the time axis 508 may representthe length of a day, or a portion of the day. For example, the time axis508 may begin at midnight and end at midnight of the next day. Inanother example, the time axis 508 may represent a period of time overwhich the lighting control devices may be turned on, or the period oftime that the natural lighting functionality may be enabled, such as aperiod of time between 6 AM and 6 PM.

The graph 504 may include an area 514 that displays a function of thecolor temperature of the lighting control devices/lighting loads at agiven time of day. The area 514 may correlate with the color temperatureaxis 506. The area 514 may track the color temperature set for thelighting control devices at the corresponding times of day when thescene is configured. The colors of the area 514 may change as the colortemperature value corresponding to the color temperature axis 506changes to indicate the relative color temperature values under the area514. In other words, according to this example, from left to right, thecolors of the area 514 change from orange to yellow to orange, matchingthe vertical height of the area relative to the y-axis values.

The graph 504 may include an indicator that displays a function of thelighting intensity value of the lighting control devices at a given timeof day. For example, the indicator that displays the lighting intensityvalue at a given time of day may be a bar, such as the bar 512. The bar512 may correlate with the intensity axis 510. The bar 512 may track theintensity value for the lighting control devices at the correspondingtimes of day when the scene is configured. Providing a separate bar 512for indicating the color temperature separately from the area 514indicating the color temperature at a given time of day, along with theseparate corresponding color temperature axis 506 and the intensity axis510, may allow for easily identifying and implementing changes inintensity apart from the changes in color temperature for the naturallighting functionality.

Though the color temperature is illustrated in the area 514 and thelighting intensity value is illustrated with the bar 512, the colortemperature and the lighting intensity value may be indicated in thesame indicator in the graph. For example, the bar 512 may track thelighting intensity values at the given time of day, while the bar itselfmay reflect/include a defined/different color temperature for eachrespective time of day (e.g., warmer colors on color temperature axis506 to reflect corresponding warm temperatures and cooler colors on thecolor temperature axis 506 to reflect corresponding cool colortemperatures). The control interface 570 may include one or morehigh-end or low-end controls. For example, as shown in FIG. 5A, theremay be a high-end color temperature box 516 a and a low-end colortemperature box 516 b. The high-end color temperature box 516 a and thelow-end color temperature box 516 b may allow the user tocontrol/change/reconfigure the color temperature settings for thenatural lighting functionality. For example, the high-end colortemperature box 516 a may represent a maximum (e.g., cooler) colortemperature at which the lighting control devices may be set over aperiod of time measured in the time axis 508 (e.g., a day). The low-endcolor temperature box 516 b may represent a minimum (e.g., warmer) colortemperature that the lighting control devices be set over the period oftime measured in the time axis 508 (e.g., a day). For example, theminimum color temperature may be 1790K and the maximum color temperaturemay be 4000K. The area 514 may have a minimum height of the minimumcolor temperature and a maximum height of the maximum color temperature.

As shown in FIG. 5A, the control interface 570 may include a high-endintensity controls, such as the high-end box 518 a and a low-endintensity controls, such as the low-end intensity box 518 b. Thehigh-end intensity button 518 a and the low-end intensity button 518 bmay allow the user to set/change/reconfigure the lighting intensityvalues of the lighting control devices over the period of time measuredin the time axis 508 (e.g., a day). For example, the high-end intensitybox 518 a may represent a maximum lighting intensity value and thelow-end intensity box 518 b may represent a minimum lighting intensityvalue that the lighting control devices may be set over the period oftime measured in the time axis 508 (e.g., a day). As shown in FIG. 5A,the minimum lighting intensity value may be 72% and the maximum lightingintensity value may be 100%. The bar 512 may have a minimum height ofthe minimum lighting intensity value and a maximum height of the maximumlighting intensity value.

One or more thresholds or triggers may be set on the time axis 508 for astarting time and/or an ending time at which changes may be made to theintensity and/or color temperature. For example, the color temperatureof natural light provided in a space by the lighting control devices maystart ramping up earlier in the day (e.g., toward a cooler colortemperature/higher intensity—i.e., the configured high end values, suchas to emulate sunrise for example) and may start ramping down later inthe day (e.g., toward a warmer color temperature/lower intensity—i.e.,the configured low end values, such as to emulate sunset for example).The thresholds may be indicated on the graph 504 by dotted verticallines. For example, as shown in FIG. 5A, the graph 504 may include a“Start Ramp Up” threshold 511, an “End Ramp Up” threshold 513, a “StartRamp Down” threshold 515, and an “End Ramp Down” threshold 517. Beforethe Start Ramp Up threshold and after the End Ramp Down threshold thecolor temperature and intensity may stay constant at the configured lowend values. Between the End Ramp Up threshold and the Start Ramp Downthreshold the color temperature and intensity may stay constant at theconfigured high end values.

Between the time of day indicated by the “Start Ramp Up” threshold 511and the time of day indicated by the “End Ramp Up” threshold 511, thecolor temperature of the lighting control devices may increase from theminimum color temperature until the maximum color temperature is met.Between the time of day indicated by the “Start Ramp Up” threshold 511and the time of day indicated by the “End Ramp Up” threshold 513, thelighting intensity value of the lighting control devices may increasefrom the minimum lighting intensity value level until the maximumlighting intensity value level is met. For example, the “Start Ramp Up”threshold 511 may be set to 4:00 AM and the “End Ramp Up” threshold 513may be set to 9:00 AM. From the time period between the “Start Ramp Up”threshold 511 and the “End Ramp Up” threshold 511, the color temperatureof the lighting control devices may increase from 2800K to 4000K and thelighting intensity value may increase from 85% to 100%.

Similarly, between the time of day indicated by the “Start Ramp Down”threshold 515 and the time of day indicated by the “End Ramp Down”threshold 517, the color temperature and/or the lighting intensity valueof the lighting control devices may decrease from the maximum colortemperature/lighting intensity value until the minimum colortemperature/lighting intensity value are met. For example, the “StartRamp Down” threshold 515 may be set to 4:00 PM and the “End Ramp Down”threshold 517 may be set to 9:00 PM. Between the time of day indicatedby the “Start Ramp Down” threshold 515 and the time of day indicated bythe “End Ramp Down” threshold 517, the color temperature of the lightingcontrol devices may decrease from 4000K to 2800K and the lightingintensity value may decrease from 100% to 85%. The colortemperature/lighting intensity value of the lighting control devices maychange linearly, step-wise, according to a sigmoid function (e.g., asshown in FIG. 5A), etc. The time periods over which the colortemperature/lighting intensity value of the lighting control devicesincreases or decreases may be automatically set, or may beuser-selected.

The graph 504 may be displayed with a default configuration for thenatural show that may be modified by the user. The default configurationmay be user defined or otherwise pre-stored. The thresholds and timeperiods over which the color temperature/lighting intensity value of thelighting control devices increase or decrease may default to emulate asunrise/sunset times at the location of the lighting control devices,and may be modified by the user. The lighting control devices may have adefault minimum/maximum color temperatures and/or a defaultminimum/maximum lighting intensity values. The default color temperaturesettings and/or lighting intensity values may depend on the types oflighting control devices implemented in the predefined zone or area.Again, the default values may be modified through interface 510 a.

Although not shown in FIG. 5A, after the color temperature, lightingintensity, thresholds, and/or time period(s) have been set, the user maysave the settings by selecting a save button. The save button may savethe current settings to the predefined area for which the settings havebeen selected. The save button may save the settings to areas that havebeen defined in the load control system with a similar area type and/orsimilar lighting control devices (e.g., area identifiers and/or deviceidentifiers). The settings may be sent to a system controller forautomatically controlling the lighting control devices in the area/areasaccording to the settings, while the natural lighting functionality isenabled. The natural lighting functionality may be overridden by otherevents (e.g., actuation of buttons for lighting control,occupancy/vacancy events, scheduled events, etc.), but may return to thestored settings for the natural lighting functionality after a period oftime. When the control of the natural lighting functionality isimplemented/configured the current time may be referenced for settingthe color temperature and/or lighting intensity value for the currenttime. The natural lighting functionality may then continue from thattime.

Graphical user interface 510 a may also include a control interface 570.The control interface 570 may include a vibrancy box 573 to select thevibrancy settings for the natural show. As shown in FIG. 5A, theactuation of the vibrancy box 573 may cause the control interface 570 todisplay an “Auto/Manual” actuator 577. If, for example, the“Auto/Manual” actuator 577 is set to “Manual” (e.g., adjustable vibrancymode is selected or enabled), as illustrated in FIG. 5A, the lightingdevices in the zone may be configured to the adjustable vibrancystate/mode and the vibrancy box 573 may include an indicator thatdisplays the range of adjustable vibrancy values, such as a vibrancy bar574. For example, the vibrancy bar 574 may include an actuator 575and/or a control line 576. The actuator 556 a may be superimposed overthe control line 576. The actuator 575 may be movable/slide-able (e.g.,here vertically movable) along the control line 576 to select differentvibrancy values along the control line 576. The vibrancy box 573 mayinclude a text box that allows the user to input the vibrancy valueand/or that reflects the vibrancy value selected by the user with theactuator 575. As described herein, when the vibrancy is set to “Manual”(as shown), the user may adjust the vibrancy settings (e.g., theintensity/contribution of the white LED(s)), and when the Vibrancy isset to “Auto” the CRI value of the emitted light may be optimizedtowards or above a target CRI value.

Increasing/decreasing vibrancy using the vibrancy bar 574 when in theadjustable vibrancy mode may increase/decrease the apparent saturationof the color of objects in the space without changing (or substantiallywithout changing) the color setting of the lighting control devices.Moving the actuator 575 upwards along the vibrancy bar 574 may increasethe vibrancy of the lighting control devices for a selected colorsetting/CCT value as the color setting/CCT value changes over time. Asthe vibrancy of a lighting control devices is increased, thecontribution of the white, or substantially white, LED(s) (e.g., yellowand/or mint green LED) of the lighting loads may decrease (e.g., given acertain color point and/or CCT), while increasing one or more of the RGBLEDs to maintain the color setting and/or lighting intensity setting ofthe light emitted by the entire lighting load while increasingsaturation. Similarly, moving the actuator 575 downwards along thevibrancy bar 574 may decrease the vibrancy value of the lighting controldevices. In addition, as the vibrancy value of the lighting controldevices is decreased, the contribution of the white, or substantiallywhite, LED(s) of the lighting control devices may increase (e.g., givena certain CCT) and correspondingly decreasing the intensity of one ormore of the RGB LEDs, while maintaining the color setting and/orintensity of the light emitted by the entire lighting load.

The selected adjustable vibrancy value may then be applied to thelighting loads over the time axis 508 based on the configured intensityand/or color of the natural show. For example, referring again to FIG.5A, the lighting loads may be set to an adjustable vibrancy value of 23%based on the configured color or intensity over the day. One willappreciate, however, that although the selection of the adjustablevibrancy value may remain the same over the period of time, theintensity or contribution of the white LED in the lighting may differbased on the selected color setting.

Although not shown in FIG. 5A, the “Auto/Manual” actuator 577 may alsobe set to “Auto” (e.g., auto vibrancy is enabled). When the“Auto/Manual” actuator 577 is set to “Auto,” the lighting controldevices may be configured to the auto vibrancy mode and thecontrol/configuration application may automatically determine thevibrancy value of the lighting control devices based on the selectedcolor setting and/or intensity value. For example, the automaticallydetermined vibrancy value may be based on a distance of the selectedcolor setting for the lighting load is from the blackbody curve on thecolor spectrum. However, as natural show changes color temperature orCCT values over time, the selected color settings for natural show maybe CCT values on the black-body curve (e.g., the distance between theselect color setting and the black-body cure is zero or substantiallyzero). The automatically determined vibrancy value may be set to apredefined value that results in the emission of light from the lightingload at or above the target CRI value at the selected CCT value. Thatis, the control/configuration application may determine a respectivevibrancy value for each of the selected color settings over the periodof time to achieve the target CRI for the given color setting at thattime. As described herein, however, this automatically determinedvibrancy value may depend on the individual LEDs within the lightingload (e.g., based on the color of each of the individual LEDs that makeup the lighting load).

In certain instances (e.g., for certain color settings or CCT values)the CRI value may be unable to be a value that is greater than or equalto the target CRI value. In those instances, the “Auto/Manual” actuator577 being set to “Auto,” may cause the lighting loads to automaticallyset the vibrancy so as to increase the CRI value towards (e.g., as closeas possible to) the target CRI threshold.

When the “Auto/Manual” actuator 577 is set to “Auto” the lighting loadsin a zone may be set to an auto vibrancy mode, where the vibrancy valuemay be automatically determined and/or may not be configurable by theuser. For example, the control line 576 and vibrancy bar 574 may bedisabled (e.g. grayed out and/or non-configurable) when the“Auto/Manual” actuator 577 is set to “Auto,” and may be enabled (asshown in FIG. 5A) when the “Auto/Manual” actuator 577 is set to“Manual.” Further, when the “Auto/Manual” actuator 577 is set to “Auto,”the vibrancy value of the lighting loads may be automatically determinedsuch that the lighting loads emit light at a CRI value that is greaterthan or above a target CRI value based on the selected CCT value forgiven time of the natural show. That is, when the “Auto/Manual” actuator577 is set to “Auto,” the control/configuration application mayautomatically determine vibrancy values as the CCT values indicated bythe area 514 change over the time axis 508. As a result, when the“Auto/Manual” actuator 577 is set to “Auto,” the user may configure thedesired CCT values over a period of time via natural show, and thecontrol/configuration application may automatically determine respectivevibrancy values such that, over the period of time, the lighting loademits light at a CRI value that is at or above a target CRI value.

As illustrated in FIGS. 5A and 5B, the CCT value during a natural showmay change over a period of time (e.g., as shown by the are 514). Forexample, the CCT value may start off flat at a low-end color temperature(e.g., as indicated by low-end color temperature box 516 b for an amountof time, then ramp up to a high-end color temperature value (e.g., asindicated by the high-end color temperature box 516 a) for an amount oftime, stay flat at the high-end color temperature for an amount of time,ramp down to the low-end color temperature for an amount of time, andfinally stay flat at the low-end color temperature for an amount oftime. When the auto vibrancy mode is enabled for natural show, thecontrol/configured application may automatically determine respectivevibrancy values for both the select low-end color temperature andhigh-end color temperature such that light is emitted at a CRI valuethat is greater than or equal to a target CRI value. In addition, thecontrol/configure application may automatically determine respectivevibrancy values as the CCT values ramp up and ramp down such that as thelighting load ramps up and ramps down, light is emitted at a CRI valuethat is greater than or equal to the target CRI value.

The user may set the time axis 508 according to a sunrise/sunset time.As shown in FIG. 5B, for example, setting the time axis 508 according toa sunrise/sunset time may cause the ramp up thresholds 511, 513 and/orthe ramp down thresholds 515, 517 to be automatically set to emulatesunrise/sunset times, respectively. The sunrise/sunset times may beautomatically set to/change with the sunrise/sunset for a definedlocation, time of year, etc. For example, the sunrise/sunset times maybe automatically set to/change with the local time for sunrise/sunsetwhere the load control system is located. The user may adjust thethresholds 511, 513, 515, 1317 relative to sunrise and sunset. The timeaxis 508 may include a predefined amount of time before and/or after thesunrise sunset for the location. The color temperatures and/or lightingintensity value may also be set based on the location, time of year,etc.

FIGS. 6A to 6I illustrate a further graphical user interface 600. Thegraphical user interface 600 may be displayed by thecontrol/configuration application 203. As described herein, the controlapplication may be running on a network device local to the load controlsystem (e.g., as illustrated in FIG. 1A) and/or an external networkdevice (e.g., which may be accessed via the cloud). The graphical userinterface 600 may be displayed and/or used to configure the lightingloads at a user's residential home, commercial office, building, etc.The graphical user interface 600 may be displayed after one or moreareas and/or zones have been configured for the load control system(e.g., the user's residential home, commercial office, building, etc.).For example, the zone configuration may include assigning the zones to acertain area, assigning lighting control devices to the respectivezones, and/or assigning/configuration of one or more control devices(e.g., a keypad).

As illustrated in FIG. 6A, the graphical user interface 600 may be usedto configure an actuator 605 of a keypad 610. The keypad 610 may be acontrol device configured to control one or more lighting loadsinstalled in a space. Also, or alternatively, the graphical userinterface 600 may be used to configure a scene that may be actuated froma network device. For example, the scene configuration may be configuredat the network device using the graphical user interface 600. The sceneconfiguration may be stored at a system controller and enabled via thenetwork device and/or enabled via a timeclock run at the systemcontroller.

As described herein, a space may be divided into one or more zones.Referring now to FIG. 6A, the keypad 610 may control one or morelighting loads in the space referred to as “Area 001.” In addition,“Area 001” may be divided into two zones for example: zone “a,” and zone“b.” Zones “a” and “b” may each include one or more lighting loads.Accordingly, the graphical user interface 600 may be used by a user(e.g., an installer of a load control system) to configure the lightingloads within “Area 001,” zone “a,” and/or zone “b.” For example, theinstaller may use the graphical user interface 600 to configure how thelighting loads within “Area 001” are set in response to an actuating ofthe actuator 605. Although not shown in FIG. 6A, different combinationsof areas and/or zones may be selected for configuration, depending onwhich actuator of keypad 610 is selected.

The graphical user interface 600 may include a configuration panel 612for configuring the programming/configuration data for performinglighting control in response to actuations of the actuator 605. Theconfiguration panel 612 may include a “Press On tab” 613 a, an “OffLevel” tab 613 b, a “Double Tap” tab 613 c, and a “Hold” tab 613 d. Eachof the respective tabs may be used to configure the settings forcontrolling the lighting loads in response to different userinteractions of actuator 605. For example, the “Press On” tab 613 a maybe used to configure the control of the lighting loads in response to a“Press On” user interaction (e.g., an actuation of the actuator 605 whenthe lighting loads are off). The “Off Level” tab 613 b may be used toconfigure the control of lighting loads in response to an “Off Level”user interaction (e.g., an actuation of the actuator 605 when thelighting loads are on). The “Double Tap” tab 613 c may be used toconfigure the control of lighting loads in response to a “Double Tap”user interaction (e.g., two successive actuations of the actuator 605).The “Hold” tab 613 d may be used to configure the control of lightingloads in response to a “Hold” user interaction (e.g., an actuation andhold of the actuator 605 for a predefined period of time). The “PressOn” configuration is described herein. Similar configurations may beperformed for the other interactions.

The configuration panel 612 may include an assignable items drop down615 a. As illustrated in FIG. 6A, if the assignable items drop down 615a is set to “Lighting—Zones,” the configuration panel 612 may displaythe lighting control settings defined for each zone, e.g., lightingloads for zone a and zone b within the space referred to as “Area 001.”In addition, although FIG. 6A illustrates an example where theassignable items drop down 615 a is set to “Lighting—Zones,” assignableitems drop down 615 a may be set to other items, such as Shade Groups,Motors, HVAC Zones, Contact Closures, Devices, Timeclocks, for example.Accordingly, the assignable items drop down 615 a may be used to performother forms of load control configuration (e.g., enable an HVAC zone,control motorized shades, etc.) in response to an actuation of theactuator 605. As described herein, the spaces, load control devicesand/or zones may have been previously configured.

The display may show the current configuration of the zones whenactuation of actuator 605 (e.g., in this case, for a “Press On”interaction). Here, the lighting loads in zone a may be configured to a100% intensity level and a CCT of 3000K in response to a “Press On” userinteraction of actuator 605. Similarly, zone b may be configured to a100% intensity level and the color point (0.133, 0.342) in response to a“Press On” user interaction of actuator 605. The configuration of eachzone may be a default configuration (e.g., based on the lighting controldevices and/or lighting loads). The configuration of each zone may beuser-defined.

The configuration panel 612 may display a “Varying Properties”indication 615 b. The “Varying Properties” indication 615 b may, whendisplayed, indicate to a user that the selected zones within a spacehave divergent configurations. For example, referring to FIG. 6A, aszone a and zone b are selected within the space “Area 001” (as shown bythe check box) and zone a and zone b have different configurations(e.g., zone a is set to a CCT of 3000K and zone b is set to the colorpoint [0.133, 0.342]), the configuration panel 612 may display the“Varying Properties” indication 615 b. In addition, as illustrated inFIG. 6A, the check marks to the left of the respective zones mayindicate that the actuator 605 is configured to control zone a and zoneb. Unchecking a zone may cause the zone to be unaffected by an actuationof the actuator.

The graphical user interface 600 may include a summary panel 614. Thesummary panel may provide a summary of the settings configured in theconfiguration panel 612 for a given context. For example, when the useris configuring the actuator 605, the summary panel 614 may provide asummary of the historical configurations defined for the actuator 605.The summary may provide a user of the graphical user interface a summaryof the lighting control settings that were configured for the identifiedactuator 605 via the configuration panel 612. As additional zones areconfigured for the actuator 605 in the configuration panel 612, thezones may be added in ascending or descending order to the summary panel614. For example, zones may be added in the order that they areprogrammed by the user of the graphical user interface 600. In addition,after the zones are added, they may be sorted. The summary panel 614 mayallow the user of the graphical user interface 612 to change and/orupdate the setting defined for the actuator being configured (e.g., theactuator 605 as illustrated in FIG. 6A). For example, as illustrated inFIG. 6A, the user may have previously configured the actuator 605 tocontrol two zones: the configurations for zones a and b in Area 001 mayinclude a 100% setting, a 2 second fade, and a 0 second delay time.

Referring now to FIG. 6B, the graphical user interface 600 may enableadjustment of the settings for configuring lighting control devices in azone after selection of the zone by the user. For example, the user mayselect zone b and the graphical user interface 600 may enableconfiguration of the lighting intensity settings (e.g., lightingintensity value), for example via the intensity drop down 615 e, colorsettings (e.g., x-y chromaticity or CCT values), for example, via thecolor drop down 615 f, fade rate (e.g., via the fade rate box 615 c),and/or delay (e.g., via the delay box 615 d) in response to a userperforming a press on of actuator 605. After selection of the colordropdown 615 f for zone b, the graphical user interface 600 may displaya “Color and Vibrancy” panel 616. The configuration panel 612 and/or thesummary panel 614 may be overlaid by the “Color and Vibrancy” panel 616.The “Color and Vibrancy” panel 616 may be displayed when a certain zoneis being configured (e.g., zone b as illustrated in FIG. 6B). The “Colorand Vibrancy” panel 616 may be displayed when the color and/or vibrancyof the lighting loads within a certain zone are being configured.Although not show in FIG. 6B, the user may configure the zone byselecting a pre-defined configuration from a dropdown list ofpre-defined configurations.

The “Color and Vibrancy” panel 616 may display a control interface 622.The control interface 622 may provide the user with the ability toconfigure a respective zone. The control interface 622 may include a“Manual Control” tab 617 a and a “Saved Colors” tab 617 b. Whenselected, the “Manual Control” tab 617 a may allow the user to manuallyconfigure the settings of a respective zone manually (e.g., manuallyconfiguring the color point, CCT, vibrancy mode, vibrancy value, etc.).Similarly, when the “Saved Colors” tab 617 b is selected, the user maybe able to configure the settings of a respective zone using a savedcolor configuration.

When the “Manual Control” tab 617 a is selected, the control interface622 may include a “Color” portion and a “Vibrancy” portion. The “Color”portion may include a “Full Color” actuator 618 a, a “Warm/Cool”actuator 618 c, a “Warm Dim” actuator 618 d and/or a “Save the Color”actuator 618 e, each of which may be selectable. When the “Save theColor” actuator 618 e is selected, the current configurations may besaved and, as described herein, accessible via the “Saved Colors” tab617 b.

When the “Full Color” actuator 618 a is selected, the control interface622 may include a palette 619 showing a plurality of colors that liewithin the color gamut formed by the various RGBW LEDs, for example,that make up the one or more lighting loads in the defined zone (e.g.,zone b, as illustrated in FIG. 6B). Superimposed over the palette 619may be an actuator 620 that identifies a user selection within the colorpalette 619. The actuator 620 may be movable/slide-able by the user toany of a plurality of locations/colors within palette 619 as similarlydescribed above for other embodiments. The graphical user interface 600may display together with actuator 620 two perpendicular control linesthat intersect at the center of the actuator 620. These control linesand the intersection point may move with the actuator 620 as it is movedby a user within palette 619 (e.g., to indicate the selected x-ycoordinates), or as the user selects another location within the palette619 independently. These control lines may assist the use in movingactuator 620 either horizontally or vertically. Accordingly, actuator620 may allow a user to configure the zone such that the zone producescolored light at a color point that lies within the color gamut formedby the various RGBW LEDs, for example, that make up the one or morelighting loads of the defined zone.

The color gamut formed by the various RGBW LEDs that make up thelighting load may be referenced using an x-y coordinate system.Accordingly, the control interface 622 may include a coordinateindicators 624 a, 624 b. The coordinate indicators 624 a, 624 b mayillustrate the x-y coordinates of the selected color. For example,referring to FIG. 5B, the color selected for zone b may be indicated bythe x-y coordinates [0.133, 0.342]. Accordingly, color may be selectedby manually inputting x-y coordinates into the coordinate indicators 624a, 624 b

Referring now to the “Vibrancy” portion of the control interface 622, an“Auto” actuator 618 b, which may be used to enable the auto vibrancymode may be included. When the “Auto” actuator 618 b is “On” (e.g., asillustrated in FIG. 6B), the control/configuration application may beconfigured to display the graphical user interface 600. In addition, thecontrol/configuration application may automatically determine a vibrancyvalue based on the selected color settings. For example, as describedherein with respect to FIG. 3A, the control/configuration applicationmay automatically determine the vibrancy value based on a distancebetween the selected color setting and the black-body curve. Asdescribed herein, the distance between the selected color setting forthe lighting load and the black-body curve may indicate whether theselected color setting has an equivalent CCT value on the black-bodycurve. If, for example, the distance is less than a distance threshold(e.g., indicating that the color setting has an equivalent CCT value),the automatically determined vibrancy value may be the automaticallydetermined vibrancy that results in the emission of light from thelighting load at or above the target CRI value (e.g., 90) for theequivalent CCT value. In addition, when the distance between theselected colors setting for the lighting load and the black-body curveis greater than the distance threshold, the automatically determinedvibrancy value may be a predefined vibrancy value (e.g., 25%) In certaininstances (e.g., for a certain color point or CCT) the CRI value may beunable to be a value that is greater than or equal to the target CRIvalue. In those instances, the “Auto” actuator 618 b being set to “On”may cause the lighting loads to increase the CRI value towards (e.g., asclose as possible to) the target CRI value. In addition, when the “Auto”actuator 618 b is set to “On,” the automatic configurations may betransmitted as they are performed, such that the user is able to theeffect of the automatic configuration at the lighting load in real time.

The user may adjust the color point of the lighting loads in a zonewhile the “Auto” actuator 618 b is “On” (e.g., when the auto vibrancymode is enabled), for example, by moving the actuator 620 eitherhorizontally or vertically within the palette 620. As the user adjuststhe color point, the “Auto” actuator 618 b being set to “On” mayautomatically adjust vibrancy of the lighting loads (e.g., to achieve aCRI value that is greater than or equal to the target CRI value). Asdescribed herein, however, if the actuator 620 is adjusted to a colorpoint or setting that farther than the distance threshold from theblack-body curve, the vibrancy value of the lighting loads may beautomatically adjusted to a predefined value. In addition, as describedherein, the “Auto” actuator 618 b being set to “On” may cause the CRI ofthe lighting loads to be increased to a value greater than or equal tothe target CRI value as the user adjusts the color point. Theseconfigurations may be subsequently transmitted (e.g., immediately orsubstantially immediately) to the lighting load(s) in a manner such thatthe user is able to see the changes at the lighting load(s) as the useradjusts the color point (e.g., make “live” changes). As describedherein, similar functionality may occur as the user adjusts the CCT oflighting loads when the “Auto” actuator 618 b is “On.”

As described herein, the “Auto” actuator 618 b may provide the user withthe option to enable the auto vibrancy mode, wherein thecontrol/configuration application may automatically determine a vibrancyvalue (e.g., which may be used to adjust the RGBW color mixing for agiven color setting) to emit light at a CRI value at or above a targetCRI value. When the auto vibrancy mode is enabled (e.g., when the “Auto”actuator 618 b is “On”), certain settings, such as adjusting vibrancyvia the actuator 626, may no longer be configurable by the user, or mayhave a limited configuration control (e.g., vibrancy limited withincertain range in which CRI value is greater than 90). Optimization ofthe CRI may or may not result in the highest CRI value. Rather, anoptimized CRI may be a value of 90 or greater based on the selectedcolor. In addition, in certain scenarios, optimizing the CRI value maydecrease the vibrancy. As a result, when the “Auto” actuator 618 b is“On,” the vibrancy of the lighting loads in a zone may automatically bechanged (e.g., increased or decreased) to the vibrancy level when theCRI is optimized (e.g., the CRI is at or above 90).

When the “Auto” actuator 618 b is “On,” the user may be provided with alimited ability to adjust vibrancy (e.g., as shown in FIG. 6B). Forexample, when the “Auto” actuator 618 b is “On,” the vibrancy controlmaybe disabled from user control (e.g., the “Vibrancy” portion may begrayed out, as shown in the example of FIG. 6B). Although the user maybe unable to control the vibrancy, the actuator 626 may move across thecontrol line 628 to indicate the automatically configured vibrancy.Whereas, when the “Auto” actuator 618 b is “Off,” the user control maybe able to adjust the vibrancy via moving the actuator 626 across thecontrol line 628. The “Auto” actuator 618 b may have two settings: “On”and “Off” When the “Auto” actuator 618 b is “Off,” vibrancy may becontrollable or adjustable by the user. When the “Auto” actuator 618 bis “On” (e.g., the auto vibrancy mode is enabled) the user may be unableto control or adjust the vibrancy.

In addition, when the “Auto” actuator 618 b is “On,” the vibrancy of thelighting loads may be automatically determined and/or may not beconfigurable by the user. The graphical user interface 600 may providethe user with the ability to configure the load controls system usinglive updates, which may allow the user to see the effects in real time.For example, when the “Auto” actuator 618 b is “On,” the network devicemay transmit control instructions to the lighting loads in a zone suchthat the lighting loads may respond to the control instructions andchange their respective states so that the user can see the effects ofthe configurations in real time.

As illustrated in FIG. 6B, the Vibrancy portion of the control interface622 may also include an actuator 626, and/or a control line 628. Andalthough not shown in FIG. 6B, when the “Auto” actuator 618 b is “Off”(e.g., adjustable vibrancy mode is enabled), the actuator 626 may beactuated along the control line 628 to control the vibrancy of thelighting load(s) in zone b. As described herein, the actuator 626 may beused to adjust the vibrancy value, which may adjust color mixing (e.g.,the relative intensities or contributions of) of the respective RGBWLEDs, which may affect the apparent color of objects within the zone(e.g., may affect the color rendering). Increasing/decreasing vibrancyvalue via the actuator 626 may increase/decrease the apparent saturationof the color of objects in the area without changing (or substantiallywithout changing) the color point of the light source. As describedherein, the effect that configuring or controlling vibrancy has on thelight emitted by the lighting load may be based on the distance betweenthe selected color setting and the black-body cure (e.g., or anotherrange of predefined values, such as the color output of a white orsubstantially white LED within a given lighting load). Accordingly,vibrancy may be enabled for lighter or less saturated colors (e.g.,colors towards the right side of the color palette 619 and/or closer tothe black-body curve). Further, the effect produced by adjusting thevibrancy via the actuator 626 may decrease as the distance between theselected color setting and the black-body curve or the color saturationincreases (e.g., colors towards the right side of to palette 619 and/orfarther from the black-body curve). Accordingly, vibrancy control may bedisabled or less controllable (e.g., the range of adjustable vibrancyvalues decreases), for selected color setting that are farther from theblack-body curve or are more saturated (e.g., colors toward the leftside of the color palette 619). For example, as the selected color pointon the color palette 619 becomes more saturated (e.g., toward the leftof the color palette 619, away from the black-body curve), flexibilityin changing the color mixing of the RGBW LEDs to increase vibrancy whilemaintaining the desired color point may be reduced, as there may befewer color mixing options of the RGBW LEDs to achieve the desired coloror CCT.

Moving the actuator 626 upwards along the control line 628 may increasethe vibrancy of the lighting loads in a zone for a selected color. Asdescribed herein, the lighting loads may be RGBW lighting loads,although one of ordinary skill in the art will understand that theconcepts disclosed herein may be applicable to lighting loads with atleast four LEDs having different spectra. For example, the embodimentsdescribed herein may be applicable to lighting loads with three discreteLEDs and a phosphor-converted LED (e.g., or combinations thereof, suchas more than four LEDs of this combination). As the vibrancy of alighting load is increased, the contribution of the white, orsubstantially white, LED(s) (e.g., yellow and/or mint green LED) of thelighting load in a zone may decrease (e.g., based on a given a certaincolor setting and/or CCT), while increasing one or more of the RGB LEDsto maintain the color point while increasing saturation. Similarly,moving the actuator 626 downwards along the control line 628 maydecrease the vibrancy of the lighting loads in a zone. In addition, asthe vibrancy of the lighting loads is decreased, the contribution of thewhite, or substantially white, LED(s) of the lighting loads in the zonemay increase (e.g., given a certain color point of CCT) andcorrespondingly decreasing the intensity of one or more of the RGB LEDs.

As the actuator 626 moves upwards along the control line 628, thecontribution of the white, or substantially white, LED(s) used to emitthe color indicated by the x-y coordinates [0.133, 0.342] may decrease.Similarly, as the actuator 626 moves downwards along the control line628, the contribution of the white, or substantially white, LED(s) usedto emit the color indicated by the x-y coordinates [0.133, 0.342] mayincrease. The user may select a color setting for a lighting load andadjust the vibrancy value of the lighting load (e.g., by moving theactuator 626 along the control line 628) at the selected color point.Also or alternatively, the user may select the vibrancy of a lightingload and adjust the color point of the lighting load (e.g., by movingthe actuator 620 across the palette 619) given the selected vibrancy. Asdescribed herein, the configuration changes may be transmitted, suchthat the user may see the change in configuration at the lighting loadsin real time.

FIGS. 6C and 6D illustrate an example of the control interface 622displayed by the graphical user interface 600 when the “Warm Dim”actuator 618 d is selected. In response to the selection of the “WarmDim” actuator 618 d, the control interface 622 may display an actuator621 for enabling/disabling warm dimming functionality at the lightingcontrol devices for a respective zone. When warm dimming functionalityis enabled, a lighting control device may receive an intensity level oran indication to adjust the intensity level and automatically controlthe color temperature in response to the intensity level or change inintensity level along the black body curve. Each intensity level maycorrespond to a given color temperature value on the black body curve.In response to selection of the “Save the Color” actuator 618 e when thewarm dimming functionality is enabled, a warm dimming parameter may bestored in the control/configuration information in the systemconfiguration data. The warm dimming parameter may indicate to thelighting control device that warm dimming is enabled and the lightingcontrol device may automatically control the color temperature along theblack body curve in response to identifying an intensity level to whichthe lighting load is to be controlled.

When the “Warm Dim” actuator is selected, the lighting control deviceand respective lighting load may be configured to a warm dim mode. Whena lighting control device/lighting are configured to a warm dim mode,increase or decreases to the lighting intensity settings (e.g., such asat the keypad 610 shown in FIG. 6A-6D), may cause the light emitted fromthe lighting load to increase or decrease along the black-body curve(e.g., increase or decrease in CCT value rather than lighting intensityvalue). Further, lighting control devices/lighting loads set to a warmdim mode may also be set to an auto vibrancy mode (e.g., as illustratedin FIG. 6C) and/or an adjustable vibrancy mode (e.g., as illustrated inFIG. 6D). When a lighting control devices/lighting loads set to a warmdim mode is also set to an auto vibrancy mode, a vibrancy value may beautomatically determined such that the lighting load emits light at CRIvalue at or above a target CRI value, which, as described herein, may bea predefined value based on the CCT value of the lighting load. And whena lighting control devices/lighting loads set to a warm dim mode is alsoset to an adjustable vibrancy mode, an adjustable vibrancy value may beselected by the user.

As illustrated in FIGS. 6C and 6D, the control interface 622 may alsoinclude the “Auto” actuator 618 b within the vibrancy setting forsetting a vibrancy setting for when warm dimming functionality isenabled at the lighting control device. As described herein, when the“Auto” actuator 618 b is “On” (e.g., as shown in FIG. 6C), the graphicaluser interface 600 may cause the vibrancy settings for a respective zoneto be automatically configured when a lighting control is performingwarm dimming. For example, given a certain CCT that is automaticallydetermined in response to an intensity level, the “Auto” actuator 618 bbeing set to “On” may cause the lighting control device to automaticallydetermine and set a vibrancy level at the CCT that increases/attempts toachieve a target CRI value of the lighting loads in a respective zone tobe greater than or equal to a target CRI value (e.g., 90). That is, the“Auto” actuator 618 b may provide the user with the ability toautomatically optimize the CRI value of the light emitted by thelighting loads in a zone towards or greater than the target CRI valuewhen the lighting control device automatically selects a CCT value inresponse to an intensity value as it warm dims. In certain instances(e.g., for certain color point or CCT) the CRI value may be unable to bea value that is greater than or equal to the target CRI value. In thoseinstances, the “Auto” actuator 618 b being set to “On,” may cause thelighting loads to increase the CRI value towards (e.g., as close aspossible to) the target CRI value.

When the “Auto” actuator 618 b is “On” (e.g., auto vibrancy mode isenabled), the vibrancy value of the lighting loads in a zone may beautomatically determined as the intensity level in the intensity dropdown 615 e changes, which may be reflected in the actuator 626 beingautomatically moved. The control application may receive the intensitylevel in the intensity drop down 615 e, calculate the corresponding CCTvalue on the black-body curve for the selected CCT value, andautomatically update the vibrancy to reflect the vibrancy value for theCCT value. Similar steps may also be performed when the intensity of thelighting load is adjusted from outside of the control application (e.g.,via buttons on a keypad). In addition, when the “Auto” actuator 618 b is“On,” the vibrancy of the lighting loads may be automatically determinedand/or may not be configurable by the user, or may be limited in itsconfiguration via actuator 626. For example, as illustrated in FIG. 6C,the “Vibrancy” portion of the control interface 622 may be disabled(e.g. grayed out and/or non-configurable) when the “Auto” actuator 618 bis “On,” and may be enabled (as shown in FIG. 6D) when the “Auto”actuator 618 b is “Off.” However, when the “Auto” actuator 618 b is “On”and vibrancy control is disabled to the user, the actuator 626 may stillbe moved across the control line 628 by the control application toindicate the automatically selected vibrancy level based on thedetermined CRI value.

As illustrated in FIGS. 6C and 6D, a lighting control device/lightingload (e.g., lighting control device/lighting load 112/114) may beconfigured to a warm dim mode. A lighting control device in the warm dimmode may be configured to control the CCT value of the light emittedfrom the lighting load. That is, when a lighting control device in thewarm dim mode receives indications to increase and/or decrease itsintensity (e.g., in response to a button press at a remote controldevice or keypad), the lighting control device may respectively increaseand/or decrease the CCT value of the light emitted from the lightingload to a corresponding CCT value on the black body curve. In addition,as illustrated in FIG. 6C, a lighting control device/lighting load inthe warm dim mode may also be configured to the auto vibrancy mode. As aresult, the lighting control device may automatically determine avibrancy value based on the CCT value of the lighting load at thecorresponding intensity value, such that the light emitted from thelighting load is at or above a target CRI value. Similarly, the lightingcontrol device may automatically determine respective vibrancy valuessuch that the light emitted from the lighting load is at or above atarget CRI value as the CCT value is increased and/or decreased with thecorresponding intensity levels. For example, in response to receiving anindication to increase its intensity, a lighting control device/lightingload configured in the warm dim and auto vibrancy modes mayautomatically increase the CCT value of the lighting load to acorresponding CCT value, as well as automatically determine an updatedvibrancy value based on the increased CCT value, such that the lightemitted from the lighting load is at or above a target CRI value. Asdescribed herein, the automatically determined vibrancy value mayincrease as the CCT value increases. The CCT values and vibrancy valuesmay similarly decrease in response to decreased intensity levels.

As illustrated in FIG. 6D, the “Auto” actuator 618 b is set to “Off,”allowing the “Vibrancy” portion to be configurable by the user when thewarm dimming functionality is enabled. For example, the “Vibrancy”portion may be used to increase and/or decrease the vibrancy of thelighting loads in a zone based on the CCT value corresponding to theselected intensity value (e.g., increase and/or decrease thecontribution of the while LED based on the CCT value corresponding tothe in the intensity drop down 615 e). The control application and/orthe lighting control device may perform the calculation of the CCT valueand/or the vibrancy in response to receiving an indication that warmdimming functionality and the user defined vibrancy value.

The lighting control parameters may be updated in thecontrol/configuration information for and stored in response to theselection of the “Save the Color” actuator 618 e. The parameters may besubsequently transmitted (e.g., immediately or substantiallyimmediately) to the lighting control device, which may generate andrespectively transmit control instructions based on the lighting controlparameters to the lighting load such that the user is able to see thechanges at the lighting load as the user adjusts the intensity of thelighting load (e.g., make “live” changes or otherwise changes theintensity of the lighting load). As described herein, similarfunctionality may occur as the user adjusts the color point of lightingloads when the “Auto” actuator 618 b is “On.”

As illustrated in FIG. 6D, when the adjustable vibrancy mode is selected(e.g., the “Auto” actuator 618 b is set to “Off”), the user may adjustthe vibrancy of the lighting loads, for example, by moving the actuator626 accords the control line 628. As described herein, increasing thevibrancy may decrease the contribution of certain LED(s) in the lightingload (e.g., yellow and/or mint green LED). Similarly, decreasing thevibrancy may increase the contribution of certain LED(s). The user mayselect a certain intensity level in the intensity drop down 615 e andthen adjust the vibrancy at the selected intensity level. Also, oralternatively, the user may select a certain vibrancy and then adjustthe intensity level in the intensity drop down 615 e given the selectedvibrancy. As described herein, the changes made by the user may be savedin response to the “Save the Color” actuator 618 e for being transmittedto the lighting control device, such that the lighting control devicecan control the vibrancy to the selected vibrancy level when thecorresponding intensity level is received.

FIGS. 6E and 6F illustrate an example of the control interface 622displayed by the graphical user interface 600 when the “Warm/Cool” tab618 c is selected. The control interface 622 may include the “Save theColor” actuator 618 e. As described herein, when the “Save the Color”actuator 618 e is actuated, the current configurations may be saved and,as described herein, accessible via the “Saved Colors” tab 617 b. Afterthe “Save the Color” actuator 618 e is actuated, for example, the usermay be prompted to name the saved configuration, which may allow theuser to identify the saved configuration during subsequentconfigurations (e.g., the configuration of other zones and/or spaces).

As illustrated in FIGS. 6E and 6F, the control interface 622 may includea palette 630, an actuator 632, and/or a control line 634. The palette630 may show a range of white colors ranging from cooler colors 630 a atthe top of the palette 630 to warmer colors 630 b at the bottom of thepalette 630. As described herein, these colors may correspond to colorsthat lie along the black-body curve. For example, the palette 630 mayshow colors along a range of CCTs on the black-body curve ranging from“warm white” (e.g., roughly 2600 K-3700 K) at 630 a, to “neutral white”(e.g., 3700 K-5000 K) to “cool white” (e.g., 5000 K-8300 K) at 630 b.The actuator 632 may be superimposed over the palette 630. The actuator632 may be movable/slide-able (e.g., here vertically movable) along thecontrol line 634 to select different CCTs along the black-body curve assimilarly described herein for other embodiments. Also, oralternatively, a user may manually input a CCT value using the input box636 a. As described herein, as the user adjust the CCT, the adjustmentsmay be transmitted to the lighting loads, such that the user is able tosee the updates in real time.

As illustrated in FIG. 6F, when the adjustable vibrancy mode is selectedthe user may adjust the vibrancy of the lighting loads, for example, bymoving the actuator 626 along the control line 628. As described herein,increasing the vibrancy may decrease the contribution of certain LED(s)in the lighting load (e.g., yellow and/or mint green LED). Similarly,decreasing the vibrancy may increase the contribution of certain LED(s).The user may select a certain CCT and then adjust the vibrancy at theselected CCT. Also, or alternatively, the user may select a certainvibrancy and then adjust the CCT given the selected vibrancy. Asdescribed herein, the changes made by the user may be transmitted to thelighting loads, such that the user can see the changes in real time.

As illustrated in FIGS. 6E and 6F, the control interface 622 may alsoinclude the “Auto” actuator 618 b within the vibrancy setting. Asdescribed herein, when the “Auto” actuator 618 b is “On” (e.g., as shownin FIG. 6E), the graphical user interface 600 may cause certain settingsfor a respective zone to be automatically configured. For example, givena certain CCT, the “Auto” actuator 618 b being set to “On” mayautomatically increase the CRI value of the lighting loads in arespective zone to be greater than or equal to a target CRI value (e.g.,90). That is, the “Auto” actuator 618 b may provide the user with theability to automatically determine a vibrancy value to optimize the CRIvalue of the light emitted by the lighting loads in a zone towards orgreater than the target CRI value. For example, as described herein, thecontrol/configuration application may automatically determine thevibrancy value based on a distance between the selected color settingand the black-body curve. However, when the “Warm/Cool” tab 618 c isselected, the selected color settings may be CCT values on theblack-body curve (e.g., the distance between the select color settingand the black-body cure is zero or substantially zero). Theautomatically determined vibrancy value may thus be set to a predefinedvalue that result in the emission of light from the lighting load at orabove the target CRI value at the selected CCT value. In certaininstances (e.g., for certain color point or CCT) the CRI value may beunable to be a value that is greater than or equal to the target CRIvalue. In those instances, the “Auto” actuator 618 b being set to “On,”may cause the lighting loads to increase the CRI value towards (e.g., asclose as possible to) the target CRI value.

When the “Auto” actuator 618 b is “On” (e.g., the auto vibrancy mode isenabled), the vibrancy of the lighting loads in a zone may beautomatically determined, which may be reflected in the actuator 626being automatically moved. In addition, when the “Auto” actuator 618 bis “On,” the vibrancy of the lighting loads may be automaticallydetermined and/or may not be configurable by the user, or may be limitedin its configuration via actuator 626. For example, as illustrated inFIG. 6E, the “Vibrancy” portion of the control interface 622 may bedisabled (e.g. grayed out and/or non-configurable) when the “Auto”actuator 618 b is “On,” and may be enabled (as shown in FIG. 6F) whenthe “Auto” actuator 618 b is “Off.” However, when the “Auto” actuator618 b is “On” and vibrancy control is disabled to the user, the actuator626 may still be moved across the control line 628 by the controlapplication to indicate the automatically selected vibrancy level basedon the determined CRI value. As illustrated in FIG. 6F, the “Auto”actuator 618 b is set to “Off,” allowing the “Vibrancy” portion to beconfigurable by the user. For example, the “Vibrancy” portion may beused to increase and/or decrease the vibrancy of the lighting loads in azone based on the selected CCT (e.g., increase and/or decrease thecontribution of the while LED based on the selected CCT).

The user may adjust the CCT of the lighting loads in a zone while the“Auto” actuator 618 b is “On,” for example, by moving the actuator 632along the control line 634. As the user adjusts the CCT, the “Auto”actuator 618 b being set to “On” may automatically adjust vibrancy oflighting loads based on the adjustments to the CCT value. In addition,as described herein, the “Auto” actuator 618 b being set to “On” maycause the CRI of the lighting loads to be increased to a value greaterthan or equal to the target CRI value as the user adjusts the colorpoint. These configurations may be subsequently transmitted (e.g.,immediately or substantially immediately) to the lighting load in amanner such that the user is able to see the changes at the lightingload as the user adjusts the color point (e.g., make “live” changes). Asdescribed herein, similar functionality may occur as the user adjuststhe color point of lighting loads when the “Auto” actuator 618 b is“On.”

FIGS. 6G, 6H, and 6I illustrate various examples of the controlinterface 622 displayed by the graphical user interface 600 when the“Saved Colors” tab 617 b is selected. As illustrated in FIGS. 6G, 6H,and 6I, when the “Saved Colors” tab 617 b is selected, the controlinterface 622 may include “Warm/Cool” tab 640 a, “Full Color” tab 640 b,and/or “All” tab 640 c. Referring now to FIG. 6G, when the “Warm/Cool”tab 640 a is selected, the control interface 622 may list the saved CCTconfigurations (e.g., CCT configurations saved by actuating the “Savethe Color” actuator 618 e, shown in FIGS. 6E and 6F). Rather thanmanually setting the CCT configuration for a respective zone using the“Manual Control” tab 617 a, the user may use the “Saved Colors” tab 617b to select a saved CCT configuration. For example, the user may selectthe “Saved Color 006” CCT configuration 641 a, which may set the CCT ofthe lighting loads in a zone to 3000k and the Vibrancy of the lightingloads in a zone to 25%. Similarly, the user may select the savedconfigurations: “Master Bedroom—Relax” CCT configuration 641 b, “SavedColor 008” CCT configuration 641 c, “Basement—Work Light” CCTconfiguration 641 d, or “Saved Color 010” CCT configuration 641 e. Thesaved colors may be exported and imported for use in other lightinginstallations or areas. As such, the names of the selected color controlsettings may allow for consistency in similar types of areas (e.g.,conference rooms, office spaces, bedrooms, etc.), as well as reduceconfiguration time.

FIG. 6H illustrates an example of the control interface 622 where the“Full Color” tab 640 b is selected. As illustrated in FIG. 6H, thecontrol interface 622 may list the saved color point configurations.Rather than manually configuring a color point for a respective zoneusing the “Manual Control” tab 617 a, the user may, for example, use the“Saved Colors” tab 617 b to automatically configure a color point byselecting a saved color point configuration from a list of saved colorpoint configurations (e.g., color point configurations saved byactuating the “Save the Color” actuator 618 e shown in FIG. 6B). Forexample, the user may select the “Saved Color 001” color pointconfiguration 642 a, which may set the light emitted from the lightingloads to the color indicated by the x-y coordinates [0.234, 0.453] andthe Vibrancy set to “Auto” (e.g., the “Auto” actuator 618 b is set to“On”). Similarly, the user may select the saved color pointconfigurations: “Saved Color 002” color point configuration 642 b,“Saved Color 003” color point configuration 642 c, “Saved Color 004”color point configuration 642 c, and “Saved Color 005” color pointconfiguration 642 d, “Saved Color 005” color point configuration 642 e,or “Saved Color 006” color point configuration 642 f.

FIG. 6I illustrates an example of the control interface 622 where the“All” tab 640 c is selected. As illustrated in FIG. 6I, the controlinterface 622 may list each of the saved configurations (e.g., includingboth warm/cool and full color settings). Rather than manuallyconfiguring the lighting loads in a respective zone using the “ManualControl” tab 617 a, the user may, for example, use the “Saved Colors”tab 617 b to automatically configure the lighting loads by selecting asaved configuration from a list of saved configurations. The list ofsaved configurations may include the list of saved CCT configurationsand the list of saved color point configurations (e.g., color pointconfigurations and CCT configurations saved by actuating the “Save theColor” actuator 618 e as shown in FIGS. 6B to 6F). For example, the usermay select the “Saved Color 003” color point configuration 642 g, whichmay set the light emitted from the lighting loads to the color indicatedby the x-y coordinated [0.349, 0.100]. Also, or alternatively, the usermay select the “Saved Color 006” CCT configuration 641 f, which may setthe CCT of the lighting loads in a zone to 3000K and the Vibrancy of thelighting loads in the zone to 25%.

A methodcomprising: receiving a selection to control a lighting load in a warmdim mode that is configured to control a correlated color temperature(CCT) value of the lighting load, wherein the lighting load comprises aplurality of light emitting diodes (LEDs); and receiving a selection tocontrol the lighting load in an auto vibrancy mode that is configured toautomatically determine a vibrancy value at which to control thelighting load based on the CCT value of the lighting load, whereincontrolling the lighting load in the auto vibrancy mode comprises:receiving an indication to change an intensity value for controlling thelighting load, automatically identifying the CCT value that correspondsto the intensity value, and automatically identifying a vibrancy valuebased on the CCT value for emitting light from the lighting load at orabove a target color rendering index (CRI) value; and controlling thelighting load according to the intensity value, the CCT value, and thevibrancy value.
 28. The method of claim 27, further comprising:receiving an indication to increase the intensity value for the lightingload; automatically identifying an updated CCT value based on theincreased intensity value for the lighting load; and automaticallyidentifying an updated vibrancy value based on the updated CCT value forthe lighting load, wherein the updated vibrancy value is higher than thevibrancy value.
 29. The method of claim 27, further comprising:receiving an indication to decrease the intensity value for the lightingload; automatically identifying an updated CCT value based on thedecreased intensity value for the lighting load; and automaticallyidentifying an updated vibrancy value based on the updated CCT value forthe lighting load, wherein the updated vibrancy value is lower than thevibrancy value.
